- TBPMH is frequently used as an initiator in the polymerization processes for styrene and its copolymers, ensuring stable results within a temperature range of 90-140°C.
- This compound is effective in initiating polymerization reactions for acrylates and methacrylates, with a working range of 100-175°C, making it suitable for various production environments.
- It is a preferred curing agent for hot-press molding applications such as SMC, BMC, and ZMC, operating between 120-170°C, delivering durable and reliable results.
- TBPMH is also employed as an initiator in the high-pressure polymerization of LDPE, particularly effective in the range of 210-270°C.
-
Packaging
(TBPMH) is generally supplied in 20 kg polyethylene drums, which provide adequate protection during storage and transport. Other packaging options can be customized based on specific client needs.
-
Storage
Ensure that the product is stored in a tightly sealed container in a well-ventilated area, with the temperature not exceeding 25°C. Keep it away from incompatible chemicals such as amines, acids, alkalis, heavy metal compounds (accelerators and metallic soaps) and avoid repackaging in the storage area.
-
Storage Stability
The product remains stable for up to three months if stored under the recommended conditions.
-
Safe Handling
Keep away from heat sources, open flames, and incompatible chemicals such as reducing agents, acids, and bases.
Handle containers carefully to avoid damage, and always refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
