1. Rigid PVC Heat Stabilizers 🧪:
Inhibit HCl degradation, offering excellent initial color retention and superior long-term thermal stability; suitable for extrusion, injection molding, and calendering; typical applications: pipes, profiles, sheets, fittings, window and door frames, flooring substrates, etc.

2. Flexible PVC Heat Stabilizers 🧪:
Balancing transparency, weather resistance, and dynamic thermal stability; suitable for extrusion, calendering, film blowing, and injection molding; typical applications: films, hoses, cable compounds, artificial leather, seals, etc.

3. Polyurethane (PU) Crosslinking/Curing Catalysts 🛠️:
Accelerate the reaction between isocyanates and polyols, improving curing rate and crosslinking density; typical systems: PU foams, elastomers, adhesives, sealants.

4. Anticorrosive Coatings/Industrial Paint Modification 🛠️:
Enhance coating adhesion and corrosion resistance, providing resistance to humidity and salt spray; suitable substrates: metal components, equipment housings, ships/marine engineering, etc.

5. Organic Synthesis and Polymer Stabilizers 🧪:
Used as reducing agents in the synthesis of thiols/thioethers/disulfides; also acts as a peroxide stabilizer, delaying polymer oxidative aging.
