April 8 (adsalecprj) -- The Dow Chemical Company announced in late March the newest addition to the NORDEL polymer family.
NORDEL 4785HM Hydrocarbon Rubber is the successor to the gas-phase grades that were the market-leading products for dense extrusion applications. NORDEL 4785HM is a high ethylene, high molecular weight polymer designed for exceptional cost performance in elastomer parts.
Dow used the technology behind NORDEL IP Hydrocarbon Rubber to design NORDEL 4785HM to have filler acceptance, cure rate and green strength, while retaining fast mixing and good low temperature properties. Designed primarily for automotive dense profiles, NORDEL 4785HM can also be used in hoses, building profiles, roofing, and molded parts. In all applications, filler and oil levels can be increased compared to 60-70 Mooney viscosity polymers for greater cost efficiency.
Some of the highlights of the new product include small pellets that mix faster than bales to save money in mixing and increase the productivity of the mixing room, a tailored molecular weight distribution to give very rapid cure, extrusion speeds and good shape retention especially in highly-filled compounds.
