Project Background：
Thermoplastic polyolefin (TPO) materials have good mechanical properties, weather resistance and processing properties due to the characteristics of both rubber and plastic, which is attracted the attention of waterproof industry. However, TPO belongs to flammable material because of low oxygen index. It is easy to produce molten droplets with flame in combustion, which will cause more losses. Therefore, the development of flame retardant TPO waterproof roll has become an inevitable trend of the entire industry in order to improve the safety of TPO waterproof roll, extend its service life and meet the increasing safety requirements of consumers.
Aims & Goals:
1. To develop a TPO efficient flame retardant masterbatch;
2. To develop a new type of composite weather resistant additive suitable for long-term high-temperature working conditions;
3. To develop a thermoplastic polyolefin waterproof roll with high flame retardancy and long service life.
