VPP foam board, also known as polypropylene (PP) foam board, is made of polypropylene (PP) as the raw material and foamed with carbon dioxide gas
PP foam board, also known as polypropylene (PP) foam board, is made of polypropylene (PP) by carbon dioxide gas. Its density is controlled in 0.10-0.70 g / cm3, thickness is 1 mm-20 mm. It has excellent thermal stability (the maximum use temperature is 120%) and dimensional stability of products under high temperature, suitable and smooth surface, excellent microwave adaptability, degradability and excellent processability.
Excellent heat resistance. Foamed PS is usually used at 80 ℃, foamed PE can only withstand 70-80 ℃, while foamed PP can withstand 120 ℃. Its compressive strength is lower than that of hard PUR and foamed PS, but higher than that of Soft PUR. Remarkable heat insulation, good resilience, and high impact energy absorption.
The use of foamed PP is very extensive. It has been applied from small to large to the hull. Foamed PP can play an important role in packaging, automobile, high-speed railway, aerospace, construction and other fields by its excellent heat resistance, sanitation, heat insulation and good environmental effect.
