PVC Application	Description
Pipe & Fittings	PVC additives help improve thermal stability, mechanical strength, and processing efficiency in rigid PVC pipes and fittings, ensuring long service life, pressure resistance, and consistent product quality.
Profiles (Window, Door, Construction)	Additives enhance weather resistance, dimensional stability, and surface finish of PVC profiles used in construction applications, maintaining performance under long-term outdoor exposure.
Wire & Cable	PVC additives provide excellent electrical insulation, heat resistance, and flexibility, supporting safe and reliable performance of cable insulation and sheathing applications.
Film & Sheet	In PVC films and sheets, additives improve flexibility, clarity, processability, and surface properties, making them suitable for packaging, decorative, and industrial applications.
Hose & Tube	PVC additives enhance flexibility, abrasion resistance, and durability, allowing hoses and tubes to withstand repeated bending, pressure, and chemical exposure.
Medical & Flexible PVC Products	Specialized PVC additives ensure flexibility, clarity, and stability required for medical-grade and flexible PVC products, while supporting consistent processing and performance standards.

PVC Additive Type	Description
Heat Stabilizers	Protect PVC from thermal degradation during processing and long-term use, improving heat resistance, color stability, and product durability.
Plasticizers	Increase flexibility, softness, and workability of PVC, allowing better performance in flexible PVC applications such as films, cables, and hoses.
Lubricants	Improve melt flow and processing efficiency by reducing friction during extrusion and molding, resulting in smoother surfaces and stable production.
Processing Aids	Enhance fusion, melt strength, and surface quality of PVC compounds, supporting higher output and improved process consistency.
Impact Modifiers	Improve impact strength and toughness of rigid PVC products, reducing brittleness and enhancing resistance to cracking and breakage.
Fillers & Extenders	Improve dimensional stability, cost efficiency, and certain mechanical properties while supporting consistent processing performance.
