Products and Technologies

PVC Stabilizers

PVC stabilizers are a central part of Tepe Kimya’s portfolio. Unstabilized PVC can undergo dehydrochlorination when exposed to processing temperatures, producing discoloration and degradation. Stabilizer systems are therefore incorporated to improve thermal stability, preserve appearance, and maintain the material’s mechanical and processing characteristics.

Tepe Kimya supplies stabilizer systems for:

• Pipes and fittings
• Window and door profiles
• Wall panels
• Technical profiles
• Cables
• Other rigid and semi-rigid PVC products

The company’s listed portfolio includes both lead-based systems and calcium-zinc systems. Lead-based stabilizers remain associated with established processing technologies in some markets, while calcium-zinc systems are used where manufacturers seek alternatives aligned with restrictions on lead-containing products. The appropriate formulation depends on processing temperature, residence time, color requirements, weatherability, mechanical performance, and applicable regulations.

Metallic Stearates

The company produces calcium stearate, zinc stearate, magnesium stearate, and lithium stearate. Metallic stearates are widely used as multifunctional additives rather than as a single-purpose product class. Their functions may include:

• Internal and external lubrication
• Mold release
• Anti-blocking and anti-tack behavior
• Dispersion assistance
• Moisture management
• Processing improvement in polymer and rubber compounds

In PVC formulations, calcium and zinc stearates can participate in stabilization and lubrication systems. In rubber, plastics, masterbatch, paper, coatings, and petrochemical formulations, product selection is influenced by particle characteristics, purity, acid value, metal content, melting behavior, and compatibility with other ingredients.

Calcium Oxide

Tepe Kimya supplies calcium oxide for use as a desiccant in rubber and recyclable-plastics applications. In these contexts, calcium oxide can react with moisture and help reduce water-related defects during processing. Moisture control is particularly relevant to recycled polymers and rubber compounds because absorbed water can contribute to porosity, surface defects, hydrolytic degradation, or inconsistent processing.

Performance depends on factors such as available surface area, particle size, handling conditions, dosage, and the moisture content of the formulation. Safe industrial handling is also necessary because calcium oxide reacts exothermically with water.

Rubber Additives and Lubricants

The company’s rubber-related products include antitack agents and specialty compounds designed to assist processing and improve the handling of rubber profiles and other rubber goods. Antitack materials help prevent unwanted adhesion between uncured rubber surfaces during storage, transport, and processing.

Lubricants supplied by Tepe Kimya are intended to reduce friction and improve processing efficiency in polymer and rubber systems. Their effectiveness depends on compatibility, migration behavior, dosage, processing temperature, and the intended balance between surface properties and bulk performance.

Applications and End Markets

Tepe Kimya’s additives serve markets in which polymer processing, compound consistency, and product durability are commercially significant.

Construction and Infrastructure

PVC stabilizers and metallic stearates are used in pipes, fittings, window profiles, wall panels, and technical profiles. These products are important in construction because PVC formulations must withstand extrusion, maintain dimensional stability, and meet requirements concerning appearance, weatherability, and service life.

Electrical and Cable Products

PVC cable compounds require controlled thermal stability and processing behavior. Stabilizer systems help manufacturers process the polymer without excessive discoloration or degradation while maintaining the required insulation and sheathing characteristics.

Rubber Products

Calcium oxide desiccants, antitack agents, lubricants, and other rubber additives support the production of profiles, seals, automotive components, and industrial rubber products. Additives can affect compound handling, extrusion behavior, surface finish, and production consistency.

Recycled Plastics and Compounding

Moisture control is a recurring challenge in recycling and polymer compounding. Calcium oxide desiccants can be used in formulations where moisture contributes to processing instability or product defects. The suitability of any desiccant depends on polymer type, recycling history, drying conditions, and the compound’s intended application.

Paper, Coatings, and Masterbatch

Metallic stearates are used in paper, coatings, and masterbatch formulations as processing aids, lubricants, dispersing agents, or surface-property modifiers. Their function varies according to the binder system, pigment or filler package, processing method, and performance requirements.

Global Presence and Market Position

Tepe Kimya has a manufacturing footprint spanning Türkiye and Malaysia, supported by trading companies in the United Kingdom and Singapore. This arrangement gives the company a presence across European, Middle Eastern, Asian, and other international supply chains without limiting its activities to the Turkish market.

The company’s participation in CHINAPLAS and other industry exhibitions supports direct engagement with polymer processors, compounders, distributors, and equipment-related businesses. Its product range places it in competition with specialized additive manufacturers and larger integrated chemical companies that supply PVC stabilizers, metallic soaps, lubricants, and rubber-processing chemicals.
