PS has excellent electrical insulation (especially high frequency insulation), colorless and transparent, light transmittance is second only to plexiglass, coloring, water resistance, and good chemical stability. The strength is normal, but the quality is brittle, and it is easy to cause stress brittleness. Not resistant to benzene, gasoline and other organic solvents. Suitable for making insulating transparent parts, decorative parts, chemical instruments, optical instruments and other parts.

PP is cheap, light, good processability and wide-ranging applications. The development of catalysts and new processes has further promoted the expansion of application fields. Some people say: "As long as there is a product whose material is replaced by Plastic, then this product will use polypropylene. potential". Main uses: woven bags, waterproof cloth, durable consumer goods: such as automobiles, home appliances and carpets.

Advantages of PP plastic box
Small density, strength, rigidity, hardness and heat resistance are better than low pressure polyethylene, can be used at about 100 degrees. It has good electrical properties and high-frequency insulation. It is not affected by humidity, but it becomes brittle, not wear-resistant, and easy to age at low temperatures. It is suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. The object is relatively hard and has a bottom when burning. Blue fire, red fire on the top, slight fragrance.
