It appears as a clear liquid. It is insoluble in water, ethanol and similar substances, but dissolves in aromatic hydrocarbon organic solvents.

 

 

 

• Special Rubber

Auxiliary vulcanizer for EPR, EPDM, silicone rubber, fluororubber etc. Shortens vulcanization cycle and optimizes mechanical properties for peroxide‑cured special rubber systems.

 

• Thermoplastics

Enhances heat, solvent, weather and flame‑retardant performance for cross‑linked PE, PP, PVC, EVA, CPE. Improves cross‑linking efficiency while cutting DCP usage and odor.

 

• Acrylate & Polyester Modification

Boosts thermal, mechanical and optical performance for acrylate products. For polyesters, it upgrades strength, dimensional stability and high‑temperature resistance for fiberglass composites.

 

• Coatings & Adhesives

Speeds up UV / EB / thermal curing for epoxy‑acrylate, PU and polyester‑based systems, improves bonding strength.

 

• Electronics & Ion‑exchange Resins

Provides excellent insulation for PCB and IC insulating materials. Substitutes divinylbenzene to prepare anti‑fouling, high‑strength ion‑exchange resin with low dosage.

 

• Impact‑resistant Polymers & Special Copolymers

Produces impact modifiers for PVC/PS via emulsion graft reaction. Copolymerizable to develop custom specialty copolymers with heat‑, weather‑ and moisture‑resistant properties.

 

 

200 kg net in metal drums; 25 kg net in plastic drums, or 25 kg net paper bags lined with PVC inner film.

 

 

Store in a cool, dry, and well-ventilated warehouse. Keep away from fire sources, direct sunlight and moisture.

 

 

 

Q1: What are the core advantages of TMPTMA compared with traditional cross-linking agents like DCP and divinylbenzene?

        TMPTMA delivers far better cross-linking efficiency than single DCP vulcanization. It effectively eliminates DCP odor, reduces peroxide dosage, and significantly improves product comprehensive performance. Compared with divinylbenzene for ion exchange resin production, it requires lower addition dosage and endows resins with superior anti-pollution, high strength, large pore size and excellent anti-corrosion properties.

 

Q2: Why is TMPTMA ideal for processing difficult-to-vulcanize special rubbers?

       Special rubbers including EPR, EPDM, fluorine rubber and silicone rubber suffer from slow vulcanization and insufficient cross-linking when using traditional organic peroxides alone. As an efficient auxiliary vulcanizer, TMPTMA shortens vulcanization cycles thoroughly and optimizes the physical and mechanical properties of finished rubber products, solving the curing difficulty of special rubber materials.

 

Q3: Can TMPTMA improve the comprehensive quality of coatings and adhesives?

       Absolutely. TMPTMA is perfectly compatible with epoxy acrylate, polyurethane and unsaturated polyester coating and adhesive systems. It supports fast curing via UV light, electron beam, X-ray or heating processes, while remarkably boosting bonding strength and overall finished product quality.
