Harwick Standard CEO keeps employees informed throughout pandemic
Harwick Standard CEO keeps employees informed throughout pandemic Details
AKRON—When the realization began to take shape in early March that the novel coronavirus pandemic had the potential to be more than just a small inconvenience, Ernie Pouttu knew that communication would be vital.
As president and CEO of Akron-based Harwick Standard Distribution Corp., he began to share emails with the firm's roughly 55 employees. Most of them are based in Akron, but a half-dozen or so work at a company warehouse in Southern California, and another seven or eight sales people are spread around the U.S.
Pouttu's messages ranged from being informational to inspirational and, at times, just a collection of his thoughts. While much of the content came from him, he also drew on other sources, including Ohio Gov. Mike DeWine's briefings, writings from a variety of publications and even some videos.
"As the president of the company, I just felt the responsibility to make sure I communicated with everybody the best I could," said Pouttu. "To just sit there and not communicate, I couldn't do that. I wouldn't have felt comfortable."

Westlake Chemical - EPOLENE® polymers
Westlake Chemical - EPOLENE® polymers Details
In EPDM compounding applications, oils are frequently used as a processing aid to improve mixing and processability. Independent laboratory studies have recently shown that the addition of EPOLENE® low molecular weight polymers can enhance mold fill performance and processability without loss of physical properties. The data generated by these studies show that just a 5 phr of EPOLENE® N-14 added to the compounding:
- Enhanced mold fill performance over control, comparable to increased oil loading of 10 phr
- Bolstered overall physical properties of the molded article vs. increasing oil levels
- Improved scorch time of the compounds vs control
Epolene Polymers for the Rubber Industry
Epolene Polymers for the Rubber Industry Details
Epolene Polymers for the Rubber Industry
In 2006, Westlake Chemical Corporation purchased the Epolene® low molecular weight polyethylene and polypropylene wax business from Eastman Chemical, introducing them into the rubber industry. Westlake has been known more prominently in the plastics business as the largest producer of low-density polyethylene (LDPE) in North America. In 2009, the Epolene line celebrated 50 years of formulation success in many diverse applications and markets. Harwick Standard has promoted the Epolene line of low molecular weight polyethylene and polypropylene waxes since 1967. These time-tested products are based on a proprietary high-pressure, free radical technology that directly creates low molecular weight polyethylene products that perform as internal-lubricant/process aids and external mold release agents in various polymeric (elastomeric) systems. These non-polar grades are soft with high penetration hardness values and low melt points that allow flow out, coating, and lubrication of the polymer chains. Epolenes are typically used in non-polar elastomers such as EPDM, synthetic Polyisoprene, Natural Rubber, Polybutadiene Rubber, NBR, SBR and Block Copolymers as well as in hot melt adhesives.
The Epolene product line is divided into 3 major classes of low molecular weight polymers: N types - Normal (non-emulsifiable), C types – Coating, and E types - Emulsifiable. The rubber industry tends to utilize the N types and C types. The flagship N-type product is Epolene N-34P (powder) which as a low-density product with a relatively low melt point (103°C) is utilized in EPDM compounds and block copolymers as well as Natural Rubber. Epolene N-11P and N-14P have demonstrated the ease with which they bloom to rubber surfaces to aid in mold release and help processing. Both Epolene N-11P and N-14P are very low molecular weight polymers with average molecular weight values of 2000 and 1700 g/mol respectively. Additionally, these grades also have found use in NBR, SBR, and Butyl rubbers.
The C type products have proven to be very good process aids. Epolene C-10 has a higher molecular weight than Epolene N-34P. This higher molecular weight delivers a robustness to the final product and allows even higher mixing temperatures to be utilized. Epolene C-10 is used in EPDM as well as other non-polar and somewhat polar elastomers including NBR, SBR and Butyl rubbers. It is particularly effective in temperature sensitive peroxide cure formulations. Typical loading levels of N and C type products in elastomeric compounds are 1.5-5.0 parts per hundred and can be used at levels as high as 10.0 parts in very demanding applications.
In addition to lubrication, many of the Epolene products when used in elastomeric systems allow for:
- ease of dispersion of fillers - improved flow properties
- reduced shrinkage - reduced tackiness during processing
- surface gloss - improved dispersion of peroxide cure systems
These products also find use in several different classes of thermoplastics including vinyls and olefins. Epolene E types, including E-14P, an oxidized low molecular weight polyethylene, and Epolene E-20, are used as internal lubricants. Furthermore, the E types typically are more compatible with PVC and aid internally as process aids. The N types, such as Epolene N-11 are less compatible and tend to aid externally as lubricants. In olefins, Epolene N-14 works very well as a mold release agent particularly for HDPE. Epolene E-43 is a chemically treated propylene based product. It performs favorably as a coupling agent for fillers in polypropylene. In addition, Epolene C-26 has been shown to help couple natural fibers in LDPE, HDPE and LLDPE.
We can provide a variety of process aids for your polymer systems, whether it is for elastomers or thermoplastics. Harwick Standard and Westlake Polymers stand ready to tackle your processing issues with solutions from the Epolene® line of products.

Synergistic Additives for Flame Retardant Elastomer Systems
Synergistic Additives for Flame Retardant Elastomer Systems Details
It is very common today to rely on a number of ingredients that are added together in an elastomeric compound to create a flame retardant product. These classical ingredients typically can be of one or two different classes of chemicals, either halogen containing or halogen-free. They can react chemically or physically to create these types of final products that are used to meet fire requirements in our industries.
The halogens today, along with other chemistries, are under a great amount of scrutiny as we strive to develop more health, safety and environmental solutions to flame retardant requirements.
When carrying out the addition of ingredients to create flame retardant compounds, one must first consider the advantages (synergism) that can take place. It is also very important to determine which ingredients may offset one another. Typically, various chemistries are combined in an effort to create a flame retardant system. During the development stage, one must consider both the advantages and disadvantages that can come about. However, the halogen containing systems are in lower favor today, as halogen-free based systems now take center stage.
The classical synergism on the chemical side is the age-old antimony oxide that must be paired with a halogen donor at a 1:3 ratio as the antimony trihalide (chlorine or bromine) is the key active ingredient. This active ingredient acts by inhibiting chain branching free radical reactions in the gas phase of the fire. It is not uncommon to rely as well on zinc borate (Firebrake ZB) which can synergistically react with antimony oxide (by partial replacement) as well with halogens. The zinc borate alternately reduces the amount of smoke generated by increasing char and giving off water of hydration to quench the flame. Rio Tinto, our supplier, confirms after recent research that zinc borate is a unique multifunctional fire retardant synergist that enhances effectiveness of existing fire retardant systems significantly by reducing fumes and smoke as well as suppressing afterglow. This is in conjunction with, and without, antimony oxide and is due to its capability to act synergistically on a multitude of fronts.
In addition, it is known that aliphatic chlorinated paraffins, (Dover’s Paroil & Harwick Standard’s CPW-100), when added to a system can act to replace at least a portion of the process oil that might be present, thereby aiding in reduction of the ignition of organic compounding ingredients.
We also need to consider the ingredients that are added at fairly high levels in halogen-free systems as they are quite efficient in the physical sense as flame retardant additives. First, phosphorus containing products play a large role in flame retarding elastomeric systems. It is very common to utilize organophosphorus compounds to replace a portion of the plasticizer content, namely phthalates, paraffinic or naphthenic process oils. They work in the gas as well as the condensed phase of a fire scenario. It has recently been determined that the newer alkyl diphenyl type phosphates, such as ICL’s Phosflex 375, is best to replace the standard isopropylated diphenyl types, Phosflex 41L, due to recently determined HS& E issues.
In addition, hydrates and hydroxides, namely Polyfil ATH from Custom Grinders, is commonly used in elastomers to quench the flame by giving its water of hydration. For higher processing temperature applications, magnesium hydroxide functions as a flame retardant and a smoke suppressant when used at high levels in some elastomer and plastic compounds. They can be used alone or with zinc borate, and have been shown to have synergistic effects.
During compound development, on one front, it is not uncommon to utilize a combination of chemical and physical reactions and the synergistic relationships to create compounds. In applications such as highly loaded EPDM roofing where one could utilize antimony oxide, chlorinated paraffins, zinc borate and fillers to aid in developing a compound that passes stringent flame retardant requirements.
Today, however, it might be more common and suggested to take advantage only of the physical interactions and create a similar flame retardant compound utilizing phosphate esters, ATH, zinc borate and fillers to create a similarly flame retardant product to be used in a myriad of industrial applications.
It is therefore, most important to consider your options and customer requirements as one should also remember synergistic effects and HS&E ramifications as you develop the flame retardant compounds for the future industrial applications.
