“New Line of Modifiers for Low Polarity Elastomers and Plastics”
This paper discusses ester-based additives to improve the properties of a number of low polarity polymers. These include elastomers like EPDM, Natural Rubber, Polychloroprene and polyolefins. Blends of thermoplastics with elastomers, thermoplastic alloys, are also targeted.
August 22, 2016 15 Technical Evaluating synthetic and
Chlorinated polyethylene, epichlorohy- drin, acrylic and hydrogenated nitrile will accept the highly polar plasticizers, but with service temperatures ranging up to 350 F, use lesser quantities and allow a more limited plasticizer choice because of plasticizer volatility characteristics.
- Are ester plasticizers good for polar elastomers?
- Ester Plasticizers for Polar Elastomers with Emphasis on Low-TemperatureEster plasticizers contribute processing advantages to rubber compounds made with polar lastomers, much the same as petroleum oils do for low polarity rubbers. By definition, a plasticizer is "a compoun
- Which polymeric plasticizer is more polar?
- ers The higher the sap value, the more polar the polymeric plasticizer. PARAPLEX G-30 was expected to have a potentially greater compatibility p blem than PLASTHALL P-550, because of its low viscosity and sap value. It might not be compatible with highly polar NBR, 38% [-CN]. PLASTHALL P-550 has been shown to
- Which polymers require high polarity plasticizers?
- with sulfur or peroxide systems. High ACN polymers require high polarity plasticizers, low ACN polymers equire low polarity plasticizers. Polymerics used at greater than 15 PHR are generally us ISTANCE T IL AND F SUCH AS: Adhesives Bla rs Conve belts and rolle Diaphragms Fuel cell liners Fuel es and es (cove and tubes) skets
- Which polymeric plasticizers are compatible with NBR polarity and viscosity?
- polymeric plasticizers in NBR is relatable to polarity and viscosity. Saponification value, in spite of what we have found thus far, is considered a measure of polarity for polymeric plastic ers The higher the sap value, the more polar the polymeric plasticizer. PARAPLEX G-30 was expected to have a potentially greater compatibility p
- What is a plasticizer used for?
- lastomers, much the same as petroleum oils do for low polarity rubbers. By definition, a plasticizer is "a compoun ng material used to enhance the deformability of a polymeric compound." The important contribution of esters, however, i
- What elastomer needs to be cured?
- 150°C for intermittent service. The elastomer requires antioxidants, antiozonants, fungicides, plasticizers, tackifiers, and lame retardants as the occasion and se erity of the application demands. It can be cure with sulfur or peroxide systems. High ACN polymers require high polarity plasticizers, low ACN polymers
