90℃ B1 Grade Anti-cracking lszh flame retardant sheath compound

Technical Date Sheet

90℃ B1 Grade Anti-cracking lszh flame retardant sheath compound

This series of products not only have excellent low-smoke halogen-free flame retardant properties, but also have excellent extrusion processing properties. It can be extruded on an ordinary PVC extruder. As long as the cooling device is normal, the extrusion processing speed can be accelerated. The performance of this product is better than similar products.

Model: SHD01-H-B1

The series are based on polyolefin and contain special halogen-free flame retardants and smoke suppressants, which are processed by precise mixing with special formulas. Its flame retardant system has excellent flame retardancy. When the cable structure is designed reasonably, it can pass the B1 type combustion test and meet the light transmittance requirements. When burning, no halogen acid gas is released, the amount of toxic and corrosive gas is very small, and the smoke concentration is very low. Has excellent resistance to environmental stress cracking and good extrusion processability. We can also provide anti-termite, anti-rodent and UV-resistant properties according to customer requirements.

1. Implementing standards: GB 31247-2014, GB/T19666-2005, IEC60502, EN50565

2. Features and uses

This product is suitable for occasions with high flame retardant requirements and low secondary hazards, such as: subways, ships, power stations, high-rise buildings, program-controlled switch rooms, computer rooms and various crowded public places. Suitable for optical cable and wire core working temperature 90 ℃ low smoke halogen free flame retardant cable sheath. This product is guaranteed to pass various beam burning tests and light transmittance tests.

3. Extrusion process

The drying temperature is 65°C and the drying time is at least 2 hours. It is advisable for the hot material to enter the extruder. It can be extruded by L/D18-25 extruder. When the screw compression is relatively low, the output is larger. Each zone of the extruder must have a cooling control system, and the melt temperature should not exceed 180 °C. Since the difference between the actual temperature of the melt and the indicated value of the temperature control table varies with the type of extruder, each user should select a suitable temperature according to the specific conditions of the extruder used. The following temperatures can be used as a reference for commissioning:

Note: If the aluminum-plastic composite inner bag’damp proof fails, it should be dried before use. The drying temperature should be 65℃ and the drying time should be at least 2 hours. It is better for hot material to enter and leave the extruder.The machine head can be without a filter screen, or a filter screen below 60 mesh can be used; the mold can be extruded or tube type.

4. Packaging, transportation and storage

Packing: N.W: 25kg/1000kg bags with inner bag of aluminum-plastic composite vacuum moisture-proof bag and outer packing being made of kraft paper composite bag or woven bag.

Transportation and storage: It should not be exposed to the sun and rain during transport. It should be stored in a clean, cool, dry and ventilated warehouse. It should be handled with care.

5. Shelf life: 6 months
