◆ UHOO PUR has been developed as a new thiourea accelerator, similar performance with ETU. ◆ UHOO PUR is used as the vulcanizing agent in the halogenated polymer. When using UHOO PUR, the high performance vulcanized rubber can be obtained in a short period of time, and scorch stability is quite good. ◆ Especially used for CR, UHOO PUR has the same characteristics with ETU. UHOO PUR is the first choice for alternative ETU with good vulcanization performance and good resistance to aging. In addition, UHOO PUR is the effective second accelerator for diene rubber, including EPDM, with no pollution, no discoloration, no bloom. UHOO PUR is used for CR and CPE to replace ETU. |
