BIPB, chemically known as 1,3-Bis(tert-butyldioxyisopropyl)benzene, is a high-performance organic peroxide crosslinking agent with CAS number 2212-81-9. Its molecular formula is C20H34O4, with a molecular weight of 338.48 g/mol. Our industrial grade product appears as a white to pale yellow powder, with strict control over purity and melting point.

As an excellent alternative to DCP (dicumyl peroxide), BIPB offers superior crosslinking efficiency with only 2/3 the dosage required for the same effect. Most importantly, it produces significantly less pungent odor during the crosslinking process and in finished products, greatly improving the workplace environment. It is widely used as a crosslinking agent for various rubbers and plastics including chlorinated polyethylene (CPE), EPDM, ethylene-vinyl acetate copolymer (EVA), silicone rubber and butyl rubber.

Our BIPB is produced with advanced synthesis and purification technology, with full batch traceability and complete supporting quality documents. We can provide customized specifications to meet specific customer requirements and ensure long-term stable bulk supply for global rubber and plastic manufacturers.

A1: For the same crosslinking effect, the recommended dosage of BIPB is approximately 2/3 of the dosage of DCP. For example, if 3 phr of DCP is used, only 2 phr of BIPB is required. The exact dosage may vary depending on the specific rubber or plastic type and desired product properties.

A2: The main advantages of BIPB over DCP are:

• Lower dosage requirement (only 2/3 of DCP), reducing production cost
• Significantly less pungent odor during processing and in finished products
• Better thermal stability
• Improved mechanical properties and aging resistance of cured products
• Lower volatility, reducing emissions during processing

A3: The typical curing temperature range for BIPB is 150-180℃. The exact curing temperature and time depend on the specific rubber or plastic type, formulation and product thickness. Post-curing may be required for some applications to achieve optimal properties.

A4: BIPB is an organic peroxide and may cause skin and eye irritation. Required PPE includes:

• Chemical-resistant gloves (nitrile or butyl rubber)
• Safety goggles with face shield
• Chemical-resistant apron and protective clothing
• Dust mask to avoid inhalation of powder

A5: In case of spill:

• Evacuate personnel to safe areas
• Wear appropriate PPE
• Sweep up and collect the spilled material carefully, avoiding dust generation
• Place collected material in suitable closed containers for disposal
• Wash the area thoroughly with water
• Do not allow product to enter drains or waterways
• Do not use combustible materials for cleanup

A6: BIPB has a shelf life of 12 months when stored in tightly sealed original containers at temperatures between 5-25℃. It should be stored in a cool, dry and well-ventilated area away from heat sources, open flames, direct sunlight and incompatible materials such as strong oxidizing agents, acids and bases. Keep containers tightly closed when not in use.
