Applications of PVC Heat Stabilizer Products

PVC (polyvinyl chloride) is widely used in various industries due to its excellent processability, durability, and cost efficiency. However, during high-temperature processing, PVC is prone to thermal degradation, resulting in discoloration, reduced mechanical strength, and the release of corrosive gases. Heat stabilizers are essential additives that protect PVC during processing and extend the performance and lifespan of the final products.

At TJCY, we offer a complete range of PVC heat stabilizers—such as calcium-zinc, lead-based, and organotin types—designed for specific application requirements across different industries.

In addition, we supply essential raw materials that support stabilizer formulation and performance, such as stearic acid, cobalt chloride hexahydrate, and trimethylolpropane (TMP).

Cable & Wire

In the cable and wire industry, PVC is commonly used for insulation and sheathing. The heat stabilizers must ensure the material resists degradation and maintains electrical properties under high processing and operating temperatures.

TJCY Recommends:

Calcium-zinc stabilizers for environmental compliance

Lead-based stabilizers for cost-effective solutions in non-EU markets

Applications:

Building wiring

Communication cables

Industrial power cables

Related Raw Materials:

● Stearic Acid: Used as a lubricant and processing aid to improve flow and thermal stability.

● Cobalt Chloride Hexahydrate: Sometimes applied in formulations requiring color-change indicators for moisture detection.

Pipes & Fittings

Rigid PVC pipes used for water supply, drainage, and electrical conduit systems require long-term thermal stability and resistance to corrosion. Our stabilizers meet safety standards and ensure long-lasting performance in both indoor and outdoor piping systems.

TJCY Recommends:

Lead-free calcium-zinc systems

RoHS and REACH-compliant solutions

Applications:

Municipal piping

Construction plumbing

Conduit protection

Related Raw Materials:

● Stearic Acid: Enhances processing, reduces friction and plate-out during extrusion.

● Trimethylolpropane (TMP): Used in some crosslinked systems for improved durability and heat resistance.

Window Profiles & Panels

PVC profiles and panels used in construction must withstand heat and UV exposure for extended periods. Heat stabilizers play a vital role in maintaining dimensional stability, color retention, and mechanical strength.

TJCY Recommends:

UV-resistant heat stabilizer packages

Combined systems with light stabilizers for outdoor performance

Applications:

Window and door frames

Exterior siding

Roofing and pergola components

Films & Sheets

Flexible and transparent PVC films demand excellent clarity, low odor, and minimal migration. Suitable stabilizers are essential to ensure optical properties and process stability, especially in food-grade and medical applications.

TJCY Recommends:

High-transparency calcium-zinc stabilizers

Organotin stabilizers for premium clarity

Applications:

Food packaging films

Transparent sheets

Medical-grade film

Flooring & Synthetic Leather

Soft PVC materials used in flooring, automotive interiors, and synthetic leather require stabilizers that maintain flexibility, surface quality, and color stability. Compatibility with plasticizers is also crucial.

TJCY Recommends:

Stabilizers designed for plasticizer-rich formulations

Long-term heat and light resistance systems

Applications:

Commercial vinyl flooring

Decorative leather

Automotive interiors

Related Raw Materials:

● TMP: Used in polymeric plasticizers and crosslinkers to enhance abrasion resistance and thermal aging performance.

● Stearic Acid: Acts as an internal lubricant to improve surface finish and process consistency.

Specialty Applications

Some applications, such as medical devices, toys, and food-contact materials, require non-toxic, heavy-metal-free stabilizers. TJCY offers eco-friendly products that comply with international safety standards.

TJCY Recommends:

REACH- and FDA-compliant stabilizers

Heavy metal-free formulations

Applications:

Medical tubing

Food-grade hoses

Toy-grade flexible PVC

Related Raw Materials:

Cobalt Chloride Hexahydrate: Sometimes used in packaging or indicators as a humidity detector or desiccant color marker.
