بررسی اجمالی
به عنوان یک عامل ولکانیزاسیون عالی برای لاستیک سیلیکونی عمل میکند و جابجایی ایمن را در 75 درجه سانتیگراد و دمای ولکانیزاسیون 90 درجه سانتیگراد فراهم میکند. دوز توصیه شده بین 1.1٪ تا 2.3٪ است. فراتر از استفاده در صنعت لاستیک، CBPO همچنین در تولید مواد لاستیکی کابلهای برق ولتاژ پایین و لاستیکهای کامپوزیت استفاده میشود.
راهنمای فنی انتخاب
معرفی محصول
Bis(2,4-dichlorobenzoyl) peroxide (CBPO, CAS 133-14-2) is a low-temperature diacyl peroxide with 4.21% active oxygen and a 10-hour half-life temperature of 47°C. Its unusually low decomposition temperature makes it the standard vulcanizing agent for silicone rubber, where it allows curing at temperatures that would degrade other initiators.
پروفایل نیمه‌عمر و دما
CBPO decomposes at 80℃ (0.1 h), 65℃ (1 h) and 47℃ (10 h) — by far the lowest in the LAAP catalogue. In silicone rubber vulcanization the compound is typically processed at around 75°C and vulcanized at 90°C, with a recommended dosage of 1.1-2.3% on rubber. Because the decomposition temperature is so low, the mixing and forming steps must be kept cool to avoid scorch; this is why CBPO is usually supplied as a 50% paste rather than a dry powder.
انتخاب در همان خانواده
CBPO (47°C) is the lowest-temperature member of the LAAP diacyl family, well below DBPB and DCP. Within the diacyl group, LPO (CAS 105-74-8, 62°C) and BPO (CAS 94-36-0, 71°C) are progressively higher-temperature options; DIPB (CAS 3437-84-1, 23°C) is even lower but far less thermally stable. Choose CBPO when the process must run below 100°C and a paste form is acceptable. Its decomposition products include carbon dioxide and 1,3-dichlorobenzene, so ventilation must be designed accordingly.
کیفیت، REACH و مستندات
CBPO is a white paste supplied at ≥50.0 ± 1.0% active content. Typical controls are assay, active oxygen and paste consistency. Each batch ships with a CoA; REACH-compliant SDS and a TDS with the half-life table and recommended dosages are available.
بسته‌بندی، MOQ و زمان تحویل
Standard packing is 20 kg fiberboard drums with a plastic inner liner, with custom packaging on request. SADT is 60°C and the recommended storage temperature is 30°C. Minimum order quantity starts at 25 kg, and quotations are returned within 24 hours.
