Product details

POLYCOM SILANE XLPE – SIOPLAS® TWO STEPS TECHNOLOGY

  • KTT200PA is the product code of PolyCom XLPE compound with granule type using for insulation in low voltage wire and cable production.
  • Silane XLPE compound – Sioplas® technology (2 steps process) – with KTT200PA code is a latest product of PolyCom that mainly made of imported high-quality LLDPE and other suitable additives such as: cross-linking agents, antioxidant, heat stabilizer, etc. and being produced from a closed production process of extruding and granulating under water.
  • KTT200PA complies with two components: Material A - 95% Silane grafted polyethylene; Material B: 5% Catalyst. Material should be used within 2 hours after mixing. Never using material if packaging bag is unsealed, broken or penetrated.
  • KTT200PA has some key features such as: easy-to-use, simple processing steps, high productivity, stable temperature, fast curing time in ambient weather temperature, much efficient for low voltage cable production under 10KV.

4. PACKAGING & STORAGE

4.1. Packaging condition

KTT200PA consists of 2 components: Grafter A~23.75 kg is contained in a vacuum sealed aluminum bag and Catalyst B~1.25 kg is contained in a small aluminum bag. Both of materials are packaged in a Kraft paper bag. Net weight of KTT200PA is 25kg.

4.2. Storage & Lifetime condition

KTT200PA should be used within 12 months from the date of production in good condition of cool and dry environment and

  • Keep in virgin sealed aluminum bag
  • Storage in warehouse condition with temperature under 35 Celsius degrees.
  • Keep out of direct sunlight or outdoor storage
  • Better to use up all material within 12 hours after opening aluminum bag. If remains, it should be sealed immediately to prevent moisture penetrated inside, the sealed bag should be used as soon as possible within 24 hours.

NOTICE:

Above specification and standard of KTT200PA product are exact based on Silane XLPE two steps technology, it is fully-tested in sheet form sample at PolyCom factory. Application of this product, upon each usage condition is varied from machine to machine, but not considerable. Accuracy rate of this product should be tested in the final product is low voltage electric cable.
