Low Volatility Processing Aid PVC Heat Stabilizer
LC-7258A is based on calcium stearate, zinc stearate, and scientifically compounded with science imported raw materials.
- Does not cause copper wire black, good electrical properties, especially suitable for UL60 ℃ - UL105 ℃ transparent wire and cable material.
- No lead, cadmium, barium, tin and other toxic heavy metals, non-nonylphenol and BPA, no odor, certified by ROHS;
- Processing and products itsself have no peculiar smell, which overcomes the mercaptan smell of organotin and the peculiar smell of general liquid stabilizer.
- High transparency, transparency can reach the same imported calcium and zinc stabilizer, close to organic tin;
- Do not migrate, water does not whitenin
- High thermal stability, the product is not easy to turn yellow;
Appearance white to light yellow powder
Metal oxide content%, ≥ 22
Volatile%, ≤ 1
Thermal stability time, ≥ 100
It is suitable for all PVC transparent product, like PVC goggles, PVC gloves, disposable sution tube and so on.
Packing and Storage:
25kgs/paper bag. Store under room temperature and dry conditions
1. What are PVC stabilizers?
Stabilizers 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.
2. What is PVC stabilizer pack?
A One Pack Stabilizer is a pack of additives added during the processing of PVC. ... Non-Toxic One Pack Stabilizers are based on Calcium, Zinc, and Barium that are blended with co-stabilizers and lubricants to make the product heavy metal free.
3. Is PVC heat sensitive?
Thermal and fire
The heat stability of raw PVC is very poor, so the addition of a heat stabilizer during the process is necessary in order to ensure the product's properties.
4. What are natural stabilizers?
Such natural hydrocolloids include agar, sodium alginate, carrageenans, guar, konjac, tragacanth, locust bean gum, psyllium, tara gum, fenugreek gum and xanthan gum. Conventional wisdom says hydrocolloids that are merely extracted from natural sources, like plants, and purified should be considered natural.
5. Why would you add a Stabiliser to plastic?
In plastics this can cause discoloration and embrittlement, which can reduce the useful lifespan of the object. Stabilizers are used to prevent this by inhibiting the various degradation processes such as oxidation, chain scission and uncontrolled recombinations and cross-linking.
6. What is a stabilizing agent?
A stabilizing agent is simply a term used as an antonym to a catalyst. Like a catalyst speeds up a chemical reaction, stabilizer inhibits the chemical reaction to provide stability. normally, it inhibits the separation of suspensions (as colloidal particles), emulsions and foams.
7. Does all PVC contain lead?
Many children's school supplies, such as lunchboxes, backpacks and binders, can be made out of PVC-a toxic plastic that is dangerous to our health and the environment. PVC contains dangerous chemical additives including phthalates, lead, cadmium, and/or organotins, which can be toxic to your child's health.
