Rigid polyurethane foam, referred to as rigid polyurethane foam, is second only to flexible polyurethane foam in the amount of polyurethane products. The rigid polyurethane foam in PMI foam is mostly closed-cell structur...
Lightweight and high-temperature resistant PMI foam materials have the best lightweight effect. In recent years, industry needs and technology have undergone rapid development. The foam sandwich composite material is a t...
1. Carbon fiber medical bed board: Because carbon fiber has the characteristics of high strength, low density, and extremely low X-ray absorption rate, in the field of medical radiation equipment, carbon fiber composite ...
Low-boiling hydrocarbons or halogenated hydrocarbons are often dissolved into plastics. When heated, the plastics soften, and the dissolved liquid volatilizes, expands and foams. For example, polystyrene foam can be prep...
1. Balsa wood, commonly known as balsa wood. Features: extremely high strength and hardness; core material foam has a small specific heat and is less affected by temperature changes; good fire resistance; good heat and s...
According to the law of foam growth and decline in the fermentation process, there are two ways to control PMI foam: one is to reduce the chance of foam formation, by adjusting the composition of the medium, such as addi...
