Safety Precautions: 1. Keep away from fire, open flame and heat source. 2. Avoid contact with reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators, metal soaps, etc.) 3. refer to the safety data sheet (MSDS) of this product. Uses: 1. Polymerization of styrene: TBPMH can be used in the polymerization reaction of styrene and copolymers of styrene, the polymerization reaction temperature range is 90-140℃. 2. Polymerization of acrylates and methacrylates: TBPMH can be used in the polymerization reaction of acrylates or methacrylates, and the polymerization reaction temperature ranges from 100-175℃. 3. Curing of thermosetting resins: TBPMH can be used for the curing of unsaturated polyesters at high temperatures. TBPMH is the preferred curing agent for UP resin thermosetting molding process (SMC, BMC, ZMC, etc.), with a temperature range of 120-170°C. The products are well tolerated, safe and environmentally friendly. 4. Vinyl polymerization initiator: TBPMH is the polymerization initiator for LDPE polymerization, with an initiation temperature range of 210-270℃. Storage conditions: Keep the package closed and in a well ventilated state, the maximum storage temperature of 25 ℃, avoid and reducing agents such as amines, acids, alkalis, heavy metal compounds (accelerators and metal soaps), it is strictly prohibited in the warehouse It is strictly prohibited to divide and take in the storage room. Storage stability: Stored according to the conditions prompted by the manufacturer, the product can be guaranteed to the factory technical standards within three months. Fire Extinguishing: Small fires need to be extinguished with dry powder or carbon dioxide extinguishers and also sprayed with large quantities of water to prevent re-ignition. Large fires need to be sprayed with large quantities of water from a safe distance away.
