Polifil ® RP-HDPE is a moderate stiffness material that retains excellent toughness. HDPE exhibits outstanding chemical resistance and environmental stress crack resistance. Injection molding applications range from small containers and lids to large crates and bins. Low melt flow versions are used for blow molded bottles for milk, cosmetics, and chemicals, and in extruded items such as pipes and profiles. High molecular weight (HMW) grades are increasingly used for high strength blown films, and large blow molded items such as drums, water tanks, and toys.

Polifil ® RP-LDPE is a soft, tough material with good clarity and high chemical resistance. LDPE remains flexible and retains impact strength at very low temperatures. High melt flow (low viscosity) grades are injection molded into products such as containers and lids. Low melt flow (high viscosity) grades are used in blown films for bags and construction, extruded sheeting and pipe, and blow molded containers such as squeeze bottles. Linear Low Density (LLDPE) resins exhibit higher strength and stiffness than traditional LDPE resins for many of these same applications.
