Plastic resin made by polymerizing styrene monomer derived from crude oil and naphtha!
We would like to introduce "PS" as a basic knowledge of plastics. "PS" is a plastic resin made by polymerizing styrene monomer, which is derived from crude oil and naphtha (raw gasoline, straight-run gasoline). Broadly speaking, there are two types: general-purpose polystyrene, which is highly transparent and hard, and impact-resistant polystyrene, which is milky white and has improved impact resistance by adding rubber components. In addition, there is syndiotactic polystyrene, which is crystalline and opaque but has excellent heat resistance. 【Features】 ■ General-purpose polystyrene (GPPS): Highly transparent and hard ■ Impact-resistant polystyrene (HIPS): Improved impact resistance by adding rubber components ■ Syndiotactic polystyrene (SPS): Excellent heat resistance *For more details, please refer to the PDF materials or feel free to contact us.
