Electrostatic problems: During the printing process, due to friction and contact, the surface of the material may be charged, adsorbing dust and impurities in the air, affecting the printing effect. Scratches and contamination: care should be taken to avoid scratches and contamination during use, s...
Molecules of plastics, for example, can be made of hundreds or even thousands of individual atoms joined together in incredibly long chains called polymers. Polythene (also called polyethene or polyethylene) is a very simple example of this. It's a polymer made by repeating a basic unit ...
From metal smooth surfaces to rough surfaces to curved surfaces, it is used in the surface protection of diversified products. No glue residue. PE (Polyethylene) is the simplest polymer organic compound, and it is the most widely used polymer material in the world today. PE protective film is...
A great low-cost 3D print material, high-impact polystyrene (HIPS) is lightweight and impact-resistant, which makes it ideal for wearables and protective cases. Also called high-density polyethylene (HDPE), it’s dissolvable with chemicals, so it’s a great temporary support material for ABS ...

2. Mechanical properties Polypropylene has high crystallinity and regular structure, and thus has excellent mechanical properties. The mechanical properties of polypropylene are higher than that of polyethylene, but it is still a low grade in plastic materials, and its tensile strength can only reach ...
PULLULAN is a colorless, odorless, neutral, linear polymer material, which is easy to absorb water and expansion and dissolves unlimitedly in water. The dissolving speed is more than twice as fast as sodium alginate and polyethylene. Its solution is not ionized, geltized, and does not crystalli...
