Is pp sheet firm after welding?

It depends on the quality of your welding.

Welding quality is good and firm.

Pure PP plate has low density, easy welding processing, excellent chemical resistance, heat resistance and impact resistance, and is non-toxic and tasteless. It is one of the most environmentally friendly engineering plastics at present.

The main colors are white and microcomputer color, and other colors can be customized according to customer requirements. Application scope: acid and alkali resistant equipment, environmental protection equipment, waste water and waste gas discharge equipment, washing tower, clean room, semiconductor factory and equipment in related industries, and it is also the first choice material for manufacturing plastic water tanks, among which PP thick plates are widely used for stamping plates, punching pads and so on.

Polypropylene (PP) extruded sheet is a plastic sheet made of PP resin with various functional additives, which is extruded, calendered, cooled and cut.

Glass fiber reinforced PP board (FRPP board): After being reinforced by 20% glass fiber, the strength and rigidity are twice as high as those of PP, and it has good heat resistance, low-temperature impact resistance, corrosion resistance and arc resistance, and low shrinkage. Especially suitable for chemical fiber, chlor-alkali, petroleum, dyes, pesticides, food, medicine, light industry, metallurgy, sewage treatment and other fields.

The shrinkage rate of PP board is quite high. Because PP board is semi-crystalline material, the shrinkage rate is generally 1.8~2.5%. And the directional uniformity of shrinkage is much better than that of PE-HD and other materials.
