One-Pack Stabilizers for PVC Cables & Wires

Plasticised PVC has been used to produce cable and wire insulation and sheathing for more than 50 years. PVC is one of the most widely used cable polymers for its excellent insulation and sheathing qualities for cables. The PVC used must possess specific characteristics to match the respective application, which can range from earthing, telecommunications, installation and heating lines, to cable for the electronics and automotive industries. The stabiliser system has a significant influence on the performance and service life of PVC cables. It allows cables and wires of high quality to be made efficiently, imparting to the finished products specific performance characteristics, such as good heat stability, good electrical characteristics, initial colour and colour stability, good mechanical properties, stabiliser dispersion and light stability.

Stabilisers are added to PVC to allow its processing and to improve its resistance especially in outdoor applications, weathering and heat ageing and have an important influence on the physical properties of PVC finished articles. Factors such as process technology involved, technical requirements of PVC end product, regulatory requirements and cost, influence the choice of the stabiliser used.
Impact modifiers used to improve the impact performance of plastics, such as PVC and PVC compounds. They provide an excellent balance of impact resistance, modulus and viscosity with an extraordinary good retention of heat distortion temperatures.
Titanium dioxide is a naturally occurring oxide of titanium. It has the highest refractive index of any material known to man, even the diamond, and is one of the whitest materials on earth. When ground into a fine powder, it transforms into a pigment that provides maximum whiteness and opacity. TiO2 pigments are used in paints and coatings, plastics, paper, building materials and many other commercial products.
