PP(聚丙烯)1100NK塑胶原料 (CAS No.None)

Product Name:Polypropylene (PP) 1100NK Resin

English Name:Polypropylene (PP) 1100NK Resin

CAS No.:9003-07-0

Aliases:Polypropylene resin, Expanded polypropylene

Molecular Formula:(C3H6)n

Physical Properties:Polypropylene is a semi-crystalline thermoplastic resin with a raw density of 0.89–0.91 g/cm³ and a melting point of approximately 165–170°C. It features low thermal conductivity, low water vapor transmission, high energy absorption, and good compressibility, together with excellent chemical resistance and flexural fatigue resistance. Foamed products can reach a density as low as about 0.47 g/cm³, with a creep modulus 3–4 times that of PS structural foam and better outdoor weathering resistance than natural wood.

Uses:Mainly used in building thermal insulation materials, such as roof insulation layers, internal/external wall insulation, and architectural formwork. Foamed PP can be processed into synthetic wood for door panels, wall panels, and roof panels. Leveraging its buoyancy and energy absorption properties, it is also used to manufacture life jackets, lifebuoy cores, surfboards, and other water rescue equipment. In addition, it is applied as thermal insulation for industrial tanks and pipelines, as well as industrial components such as gaskets and anti-vibration pads.
