SDL 900 TS/7White uniform powder0.32 g/cm34.0~6.0phrElectrical wire & power cable sheaths
SDL 900 TS/9White uniform powder0.32 g/cm34.0~6.0phrPower cable sheaths
SDL 900 TS/10White uniform powder0.30 g/cm38.0~15.0phrHigh temperature insulating wire & cable insulation materials
Advantages
  1. SDL 900 series products are Ca-Zn composite thermal stabilizers specially designed and manufactured for raw materials of all grades PVC wire cable according to the national standards HR70,H70,H/90,H//90and J90.
  2. They can ensure excellent insulating performance. They have excellent long-term thermal stability and Congo red test time. Through the strengthening design of anti-heat aging stability of PVC resin, they can maintain high melt tension in high speed extrusion process, thus to ensure excellent mechanical tensile strength of the final products.

  3. They have good resistance to discoloration, suitable for manufacturing all kinds of bright sheath materials, and stronger resistance to UV and weather.

  4. SDL 900 series products do not contain lubricant, so customer can add the appropriate paraffin wax or PE wax as needed to adjust rheological properties.

Uniadd SGC 100

SGC 100 series  Ca-Zn composite thermal stabilizers are designed and manufactured according to the advanced concept of environmental protection. They are free of lead, cadmium, barium, tin and other heavy metals and harmful compounds. SGC 100 series products achieve the latest European REACH: SVHC (168) environmental protection standards by SGS test.

Application
SGC 100 EP/6White uniform powder0.6 g/cm32.5~3.5phrSmall & medium caliber rigid PVC pipes
SGC 100 EP/9White uniform0.6 g/cm32.5~3.5phrMedium & large caliber rigid PVC pipes
Advantages
  1. SGC 100 series products which have excellent thermal stability and tonal stability are suitable for rigid PVC pipes of small, medium and large calibers in extrusion process;

  2. SGC 100 series products have strong commonality, suitable for processing all kinds of PVC resin, and their thermal stability and tonal stability won’t be restricted and influenced by the type and dosage of filling agents such as calcium carbonate. They have strong compatibility which can be used together with lead-based or organotin stabilizer and give rise to synergistic effect;

  3. SGC 100 series products are given good supporting internal and external lubrication balance system. They provide wide process conditions to the rigid PVC pipes in extrusion process, and ensure the internal and external walls smooth and gloss;

  4. No precipitation during the extrusion process. They can maintain the balance of plasticizing and lubrication, guarantee the physical characteristics of the final products. Enhance the white color brilliance and fastness. They are equipped with light stabilization function and stronger resistance in outdoor weather.

Uniadd SGJ 500

SGJ 500 series Ca-Zn composite thermal stabilizers, use proprietary design ideas. They are free of lead, cadmium, barium, tin and other heavy metals and harmful compounds. SGJ 500 series products achieve the latest European REACH: SVHC (163) environmental protection standards by SGS test.

Typical Property & Application
GradesAppearanceApparent Density
Recommended Dosage

Application
SGJ 500 SP/5White uniform powder0.35 g/cm34.0~6.0phrSmall and medium rigid PVC pipe fittings
SGJ 500 SP/8White uniform powder0.34 g/cm34.0~6.0phrMedium and large rigid PVC pipe fittings
  1. SGJ 500 series products are especially suitable for white rigid PVC pipe fittings, not restricted and influenced by filling agents such as calcium carbonate, which have excellent early, medium-term tonal stability, long-term thermal stability, and strong commonality;

  2. Good dispersion and no precipitation. They can enhance the color degree and fastness of white color. In addition, they are equipped with light stabilization function, resistance to the pollution of sulfide and heavy metal and stronger resistance in outdoor weather;

  3. SGJ 500 series products have phase structure interface active mechanism, good dispersion, inclusion of the products with PVC resin, and toughening and promoting melting effect which can greatly improve plasticizing uniformity and high-speed molten liquidity of the mixture, and ensure the uniform wall thickness and high smooth surface of products;

  4. The unique design concept and formula technology can effectively restrain the zinc from burning and PVC chain from rupturing, so SGJ 500 series products can fundamentally ensure the chemical stability of PVC resin, maintain the consistently high melting body strength of the plasticizing molten body under high speed and high temperature shear, and also enhance the product physical properties such as tensile strength and resistance to water pressure blasting.
