Solubleness of TBPB:
Soluble in alcohol, ester, ether, organic solvents.Does not dissolve in water.
1. Polymerization of styrene
TBPB can be used for the polymerization and copolymerization of styrene in the temperature
range of 100-140°C. During polymerization the temperature is increased in steps.
2. Polymerization of acrylates and methacrylates
TBPB can be used as initiator for the solution (co)polymerization of acrylates and
methcrylates in the temperatures range of 100-170°C, amongst others for the coatings.
TBPB can also be applied as an initiator for the bulk and suspension (co)polymerization of
acrylates and methcrylates.
3. Polymerization of ethylene
TBPB is an efficient initirtor for the ethylene polymerization under high pressure in both
autoclave and tubular processes.
To obtain a wide spectrum of polymerization temperatures, combinations with other peroxides
are applied in practice.
Depending on reaction conditions. TBPB is active in the temperature range of 220-270°C.
4. Other applications
TBPB can also be used for the (co)polymerization of acrylonitrile and vinyl acetate.
5. Crosslinking Peroxides
TBPB,is suitable for crosslinking of EPDM rubber compounds at ambient temperature within
some weeks.
Rubber compounds containing TBPB have moderate processing safety in combination with a
very high speed of cure.
6. Peroxides for Thermoset Resins
TBPB, tert-butyl peroxybenzoate, is an aromatic perester, which is used for the curing of
unsaturated polyester resins at elevated temperatures.
TBPB is preferred for the curing of UP resin based Hot Press
Moulding formulations (SMC, BMC, ZMC etc) in the temperature range of 120 - 170°C
Packaging & Shipping

Since 1999 we entered into EPS business line, we have involved in this industry for more than 12 years. Our company mainly focus on EPS scientific research and development, technical support, and EPS consult information.
In China, we are familiar with domestic developing trends of EPS industry. Here we emphasize on the promotion of EPS raw materials and advanced equipments from abroad, and we help our customers to solve some technical problems during processing, even produce some colored materials for them according to their clients' Demands. We are concerned about EPS raw material prices trends at any time, thus we help our customers save raw material purchasing costs and procurement costs. With many years' Cooperation experience with major shipping companies like MAESK, MSC, COSCO, etc., we ensure our cargoes booking and sailing timely. Through all these efforts so that we can enhance our customers' Competitiveness.
Abroad, we are committed to the promotion of the EPS block machine, packaging machine and automatic cutting line origin from China with Chinese characteristics, high quality & reasonable price. We have erected a bridge for worldwide EPS users engaged in EPS industry to communicate better with each other. Therefore, our customers save a lot of travel costs and time, especially reduce a large number of losses due to quality claims in the disputes with our familiar Chinese laws. We' Re not proud of selling cheap products to our customers, but proud of helping our customers solve purchasing problems.
We also devoted a lot in recycling EPS waste. We gather waste EPS in China, and promise to our customers to recycle waste EPS around the world. We processed these waste EPS into a variety of beautiful and useful products. In this point, we pride for reducing the white pollution, and saving energy for the community.
In China, only a company like us, can engage in areas range from raw materials, equipments and recycling granulations with technical supports, and play endless important role in the whole industrial chain.
Concentrate, so we are professional. You are always our concern centre.
