Birch Plastics High-Impact Polystyrene (HIPS) Regrind is a rubber modified version of GPPS (general purpose polystyrene). The addition of rubber to the formula increases the impact strength and flexibility.

Birch Plastics Polypropylene Copolymer (PPC) Izod is a bit softer than PPH, but it has greater impact strength and is tougher and more durable than homopolymer polypropylene. Copolymer polypropylene tends to have better stress crack resistance and low-temperature toughness than homopolymer at the expense of small reductions in other properties.

Birch Plastics High-Density Polyethylene (HDPE) is the sturdiest and most inflexible type of polyethylene within polyethylene applications. Its sturdy and moderately robust character can be used for a wide range of applications. HDPE is defined by having a density greater than or equal to .941 g/cm3. High-density polyethylene (HDPE) represents the most common portion of the polyethylene applications. HDPE offers excellent impact resistance, lightweight, low moisture absorption and high tensile strength. Additionally, HDPE is also nontoxic and non-staining.
