Material Notes:
Elvax® resins offer a unique combination of processing and performance characteristics. They provide outstanding toughness and resilience and maintain flexibility over a broad temperature range without the need for plasticizers.Elvax® resins can be used alone or to improve the flexibility, resilience and toughness of other resins. Depending on the demands of the particular application, they can be pigmented, foamed, filled, and/or crosslinked. In addition to their performance advantages, Elvax® resins are processed easily using conventional thermoplastic processing techniques, i.e., injection molding, extrusion and foaming, as well as rubber processing techniques, i.e., Banbury mixing, foam extrusion and molding.Test specimens except for tensile impact where prepared by compression molding (ASTM D1928, procedure C). Tensile impact samples were injection molded.Processing Information:Molding and ExtrudingModified and unmodified Elvax® resins can be processed in conventional thermoplastic and rubber processing equipment. The temperature profile will vary with machine type, size and screw design as well as with part size, thickness or configuration.CompoundingElvax® resins are compatible with a variety of other resins and elastomers including polyethylene, polypropylene and styrene-butadiene rubber. Clays and other inorganic fillers can be added to improve abrasion resistance and lower cost.Foaming AgentsElvax® resins are readily foamed using chemical or physical blowing agents.Crosslinking AgentsPeroxides such as "Di-Cup"† and "Vul-Cup"† dicumyl peroxide can be used to crosslink or vulcanize Elvax® resins.(†Hercules Inc.)
