Data in this brochure can not be used for standard purposes.Physical and chemical property:

Appearance: white or light yellow powder

Odor: None

Average granularity: 1.5 micrometer

Specific gravity: 2.5 (sp.gr)

PH value: strong alkalinity

Main features:

It is an inorganic compound and excellent acid absorption agent. It can effectively block zinc combustion during processing;

It enjoys excellent heat stability under high temperature and can reach about 400 . It is particularly applicable to hard processing ingredient;

During joint utilization with ST-220, it can play a good synergism role to heat resistant stabilizer.

It is applicable to addition of Ba-Zn and Ca-Zn series ingredients; during the application of Ba-Zn and Ca-Zn series hard ingredients, it can better demonstrate the unique effect;

It enjoys advantageous acid supplementation (acid elimination) features and enable soft PVC ingredient to turn yellow or red in the initial period given its innate alkalinity;

Under the temperature condition of above 350, it will not produce air bubble separation such as CO2 and H2O. therefore, it can effectively serve as the hard PVC auxiliary stabilizer under high processing temperature.

Scope of application:

It can upgrade the long-term stability of Ba-Zn and Ca-Zn stabilizer in Ba-Zn and Ca-Zn hard ingredients.

Addition volume:

0.2% (to total volume)

Packaging:

20kg/bag

Technological service

1. It has the “cloning” composite heat stabilizer!

2. It can provide the technologies concerning melting stearate, composite stabilizer, polyethylene wax, aluminate coupling agent and borate ester coupling agent.

The materials are compiled according to knowledge mastered by us at present and only for reference! We do not offer any guarantee. We reserve the right to change product parameters within the scope of technological progress or product development. Since we can not control the processing conditions and coordination raw materials in a wide range, the user has to first test its applicability before normal production.
