Recycled HIPS Styrofoam Fountain Pen Tube

1/

Styrofoam is expanded polystyrene(PS), which is one of the five general-purpose plastics. The resin identification code of Styrofoam is 6, The heat resistance range of PS is between 70-90℃, the texture of PS is hard and brittle, it has low impact strength, and poor heat resistance. The recycled PS is polymerized by adding poly butyl rubber reinforcement, which has made into impact-resistant polystyrene (HIPS). It can be injected and molded into plastic products, such as pen shells. more
