Feature
Dry silane XLM30+2 is free-flowing granules masterbatch with high silane active content with many advantages as below:
1. Quicker incorporation during mixing and more uniform distribution.
2. Greater accuracy in measuring rather than liquids.
3. Improved processability, safety and convenience.
4. Lower pollution and user-friendly.
XLM31 Dry Silane masterbatch contains no antioxidant so it has to be used in conjunction of a stabilized LLDPE grades. In case of using unstabilized LLDPE grades a dedicated antioxidant or antioxidant/metal deactivator master batch has to be added.
Application
It is mainly used for crosslinking of low- and medium-voltage power cables based on stabilized polyethylene resins. Improves stability. Prevents premature crosslinking.
Dosage
Depending on the formulation and performance target, a dosage level of 1~2% active silane is needed (e. G. When using XLM31LL1, an addition of 2.5- 5 % is recommended).
Packing
This product is available in 20 kg aluminum foil bag and 200 liters steel drum. Other custom-tailor packing is possible on special request.
Storage and shelf life
Should be stored in dry, cool, ventilated room; Keep away from water, moisture, high temperature and fire. Packages already opened should be used up immediately; Otherwise this product will react with the moisture in the air and will be not qualified for use.
This product has a shelf life of at least 6 months in the original packing.

Mono Calcium Phosphate ,the chemical formula is Ca (H2PO4)2.H2O, molecular weight of the body is 252.06, after dryed the product is white or slightly yellow micro powder or granules, the relative density of 2.22 (16 °C). Slightly hygroscopic, soluble in hydrochloric acid, nitric acid, slightly soluble in cold water, almost insoluble in ethanol. At 30 °C, 100 ml of water soluble MCP 1.8g. The aqueous solution was acidic, heating the aqueous solution can get calcium hydrogen phosphate. Lose crystal water at 109 °C and decomposed into calcium metaphosphate at 203°C. Applications:Monocalcium Phosphate is used to supply mineral nutrition such as phosphorus (P) and calcium (Ca) for animal, which can be easily digested and absorbed. Extensively applied as additives of Phosphorous and Calcium in aquatic animals feed.Higher water solubility of MCP is required in aquatic animals feed.
