Huafu Chemicals has been committed to the melamine industry since 2000.
The main differences between 100% melamine (called A5 material in China) and 50% melamine or 30% melamine (commonly known as A1 material or A3 material in China) are as follows:
1. Different composition:
The main components of A5 are melamine formaldehyde resin (melamine formaldehyde resin) about 75%, pulp (Additives) about 20%, and additives (ɑ-cellulose) about 5%; cyclic polymer structure.
The main components of A1 are urea formaldehyde resin (urea formaldehyde resin) about 75%, pulp (Additives) about 20% and additives (ɑ-cellulos) about 5%;
2. Different heat resistance:
A5 heat-resistant 120℃, A1 heat-resistant 80℃;
3. Different sanitary performance:
A5 can pass the national hygienic quality inspection standard, A1 generally cannot pass the hygienic performance test, and can only produce products that do not come into direct contact with food
