EPDM (ethylene propylene diene monomer)
Excellent weather resistance (UV and ozone resistance), good elasticity, suitable for sealing strips, waterproof materials, and automotive accessories.
HDPE (high-density polyethylene)
Lightweight, chemical corrosion resistance, good low-temperature toughness, commonly used in water pipes, packaging bottles, and chemical storage tanks.
PP (polypropylene)
High temperature resistance (120°C), good rigidity, food-grade safety, suitable for food containers, medical supplies, and automotive parts.
PVC (polyvinyl chloride)
Low cost, can be hard or soft, but poor weather resistance, hard PVC is used for building materials, soft PVC is used for wire skins, films, etc.
Summary in one sentence:
EPDM has good weather resistance and elasticity, HDPE is corrosion-resistant and lightweight, PP is high temperature resistant and safe, PVC is cheap but afraid of the sun
