Product information:
SILIKE SLK1123 is a special type of silicone gum with ultra-high molecular weight
and modified structure.
Product benefits
1. The molecular weight of raw gum is higher, and the content of vinyl is
reduced, so that the silicone gum has fewer crosslinking points, less
vulcanizing agent, lower yellowing degree, better surface appearance,
and higher grade of product under the premise of maintaining strengt
h;
2. Volatile matter control within 1%, the product smell is lower, can be u
sed in high VOC requirement applications;
3. With high molecular weight gum and better wear resistance when appl
icated for plastics;
4. Molecular weight control range is stricter, so that the strength of produ
cts, hand feeling and other indicators more uniform.
5. High molecular weight raw gum, keeps non-stick, used for color maste
r raw gum, vulcanizing agent raw gum with better handling.
Features
Insoluble in water, soluble in toluene and other organic solvents, its p
roducts have small compression deformation, excellent characteristics of re
sistance to saturated water vapor, flammable in case of fire or high heat.
Applications
1. Low vinyl content, high molecular weight, suitable for the color maste
rbatch raw gum, vulcanizing agent raw gum with excellent handling,
non-stick performances;
2. Suitable for silicone masterbatch raw gum;
3. Low vinyl content, suitable for the manufacturing of low hardness silic
one products;
4. Ultrahigh molecular weight, suitable for adding in plastic to improve w
ear resistance and processing performance.

Description
LYPA-208C is a special silicone polymer dispersed in LDPE, It is widely used as an efficient lubricant in XLPE cable compounds . When the dosage at 0.1 to 1.0%, it can improve the processing properties including better mold release, reduced extrusion torque , less die drool ; at a higher loading at 1-5%, It can enhance surface quality such as more slip, lower COF, improve abrasion resistanc....etc
Benefits
The linear structure of LLDPE will turn into a three-dimensional cross-linking network after
Silane-grafting and cross-linking reaction, in this way poor flow of resin result poor processing, and the compounds are easily adhere to the screw groove and mold dead corners and form dead mass which will affect the extruded cable appearance ( rough surface with little pre-crosslinking particles which formed at cross-linking step ), so effective lubricant like LYPA-208C added to improve the processing
How to use
Addition levels between 0.2~5.0% is suggested . It can be used in classical melt blending process like Single /Twin screw extruders, injection molding. A physical blend with virgin polymer pellets is recommended . For better result , pre-drying is recommend for 1 hour at 70-75
