Ⅰ. Purpose;
Our company's newly developed water-based high-efficiency Type IV terminator contains highly effective free radical
scavengers. It demonstrates excellent compatibility with systems, rapidly penetrates into the system to terminate reactions,
and features low dosage, superior termination efficacy, and excellent resin whiteness, offering exceptional cost-effectiveness.
The product requires only 1/2 to 1/3 of conventional terminators, significantly enhancing PVC manufacturers' economic
benefits. Since its market launch, the product has been widely embraced and highly praised by users.
II. Quality Indicators:
Appearance: Colorless or light brown transparent liquid
pH:>12
Ratio: 1.0-1.1
Active ingredient content:>20%
Ⅲ. Usage:
When the conversion rate of PVC synthesis reaction reaches about 80%, the polymerization reaction is stopped immediately
by adding a terminator, which reduces the proportion of unstable structure in PVC and improves the thermal stability of the
resin.
IV. Packaging and Storage:
The product shall be packaged in 200kg dark plastic drums or as required by the user. It shall be stored in a cool, dry place,
protected from sunlight and rain. The shelf life of this product is 12 months.
Ⅴ. Recommended dosage per reactor for common domestic reactor types:
The 70-cubic-meter vessel holds 15-20 kg, while the 105-cubic-meter vessel holds 25-30 kg.
