According to car component different, get together the requirement that ammoniac fat gets used to a car with the different pattern such as expanded plastics, elastomer, adhesive and function, get together for instance ammoniac fat the expanded plastics change as the recipe, have quality light, adiabatic, resilience is good, comfortable quality good, durable, security mixes function of good, low temperature suck brace up the gender is more advanced characteristic, other data cannot compare its advantage.
The useless expanded plastics of car and home appliance product reclaims already more and more get the attention of people. Recently, business of foreign car production can have reclaimed use 30 ％ reclaim useless expanded plastics.
