PP plastic has the characteristics of low density, non-toxic, colorless, odorless, corrosion resistance, and good heat resistance. Through flame retardant modification, it can be applied to components with flame retardant requirements in home appliances, automobiles and other fields to meet the requirements of electrical products. , At the same time to achieve the most optimized economic effect.

Plastic hollow board is a new type of environmentally friendly plastic sheet made of thermoplastic PP (polypropylene), non-toxic, non-polluting, hollow structure, rich in colors, waterproof and moisture-proof, anti-aging, corrosion-resistant, and strong bearing capacity. It is widely used at home and abroad. Many companies are using hollow board products, how to distinguish the quality of hollow board? It has become a problem for many companies, and there are a few points to share with you.

1. By firing:, a good hollow board is as thin as a hairline and the drawing is still colorful and smooth. The inferior hollow board produced from waste is dim in color, rough in drawing, and carbon-like.

2. By looking: The color of the high-quality hollow board is purer, the surface is smoother, and there is no graininess. Inferior hollow board has rough surface and dim color.

3. By pinching: pinch on the edge of the hollow board with the same strength, inferior quality is easy to deform, and the hardness is not enough. The high-quality hollow board is not easy to deform, and the bearing strength is large.
