Product description:
TDDS is a vulcanizing crosslinker specially designed for halogenated synthetic rubber such as chlorinated polyethylene rubber (CM) and chlorohydrin rubber (ECO) chloroprene rubber (CR) chlorosulfonated polyethylene rubber (CSR). TDDS is a derivative of 2,5-dimercapto-1,3,4-thiadiazole ester.
TDDS is a derivative of thiadiazole ester. It can be used as a new vulcanization crosslinker for halogenated polymers such as chlorinated polyethylene rubber (CPE), polyvinyl chloride (PVC) and chlorohydrin rubber (ECO), chlorosulfonated polyethylene rubber (CSM), chlorinated rubber, chlorobutadiene rubber (EVA). TDDS is especially suitable for vulcanization and crosslinking of CPE. It is a highly effective and high performance vulcanizing agent for chlorinated polyethylene with NC or BF.
Advantages of TDD vulcanization system:
1. TDDS vulcanization system is suitable for any vulcanization methods, such as moulding, continuous vulcanization, tank type, microwave type, etc. The vulcanization process will not be oxidized by air. It is suitable for Moldless vulcanization in vulcanization tank with low vulcanization temperature. Also suitable for injection moulding can be vulcanized in vulcanizer.
2. The curing speed is fast and the positive curing time is short.
3. Safe operation, no pollution in the production process, no irritating odor, no frost, no scorch.
4. The physical properties of vulcanizates are as good as those of peroxide systems, and they are ageing-resistant. Excellent heat resistance, small compression permanent deformation, especially good tear resistance.
5. The product has good appearance, no frost spraying, no burning and no irritating odor.
Product applications:
1. The recommended dosage is 2.0-2.5 TDDS and 1.5 BF (NC) for cable sheath and rubber products such as inner and outer rubber and conveyor belts.
2. A small amount of insoluble sulfur can be used in braided rubber pipes with copper-plated steel wires to improve their vulcanization and adhesion to steel wires.
3. Suitable for high temperature and rapid vulcanization, and also for steam tank type vulcanization: 4 kg/cm2 steam pressure (151 C) vulcanization tank. Suggestion of vulcanization time is 40 minutes.

Applications: PDM as a function of rubber chemicals in rubber processing for the curing agent can also help the system can be used for peroxide curing agent, also can be used as anti-scorching agent and tackifier, both for general-purpose rubber, also applies to special rubber and rubber and use system. In natural rubber, and sulfur coordination to prevent reversion to improve the heat resistance, reduce heat, anti-aging, improve adhesion of the rubber and tire cord and the vulcanized rubber modulus. Shoulder for load tire rubber, rubber buffer layer, solve the problem of bias truck tire shoulder separation can also be used for large-size thick natural rubber products and various rubber sundries. PDM can be used as auxiliary curing agent, can significantly improve the correlation performance, increase heat resistance, suitable for high temperature curing system, reducing the compression is very obvious, but also reduce the amount of peroxide, preventing the processing of rubber in the focus burning, improve tire cord and rubber and metal bond strength. PDM is a non-sulfur vulcanizing agent for rubber cable, it can replace thiazoles, thiuram and all sulfur vulcanizing agent, solution of copper wire and copper electrical generation due to exposure to sulfur vulcanizing agent black copper sulfide contamination problems. As scorch agent for the 0.5-1.0 copies, as curing agent for the 2-3, to improve the compressive deformation of 1.5 copies, improve the adhesive strength of 0.5-5.0 copies.
