Product name, item and use

Product introduction

This series of materials are based on polyolefin elastomers, which are added with flame retardants, smoke suppressants, antioxidants, rodent and ant auxiliary materials, and processing aids, and are mixed and plasticized to granulate. It not only has excellent physical and mechanical properties, electrical properties, flame retardant properties and processing performance, but also has high environmental protection features such as halogen-free and low smoke generation.

Extrusion process

When the storage environment is wet or the production surface is required to be high, the particles can be dried in a hot air hopper at 70 ℃ for 1-2 hours.

It is recommended to use a low compression ratio screw extrusion with a compression ratio of 1.2-2.0:1.Before extrusion, the screw should be cleaned to ensure the cleanliness of the product. It is recommended to use 80 mesh or 100 mesh filter screen to avoid impurities in the extrusion process, and to ensure the melt pressure to obtain a good appearance and material density.As the difference between the actual temperature of the melt and the indicated value of the temperature control table varies with the type of extruder, the user is requested to select the appropriate temperature according to the specific situation of the extruder used.The following temperatures can be used as reference for start-up and commissioning:

Packaging and storage

(25 ± 0.2) kg / bag, inner aluminum plastic composite bag, outer kraft paper bag (or customer specified packaging)

Product performance

Note: The above data is a typical value obtained by testing the product and is not a standard for testing restrictions.

A rodent-resistant application comparison test was conducted for rodent-proof, ant-resistant, low-smoke, halogen-free and flame-retardant polyolefin sheath material (YHS70012HFSY). During the test, the rats did not find any poisoning and death, and moved freely and their diet was normal. After the sample was placed for 24 hours, the plastic coating of the control sample was bitten open and the copper wire was exposed; after 72 hours, the plastic coating was completely bitten and the copper wire was completely exposed; and no rat was found in the plastic with the anti-rodent agent added Traces of biting.

For rodent-proof, ant-resistant, low-smoke, halogen-free and flame-retardant polyolefin sheath material (YHS70012HFSY), the ant-proof application test is carried out in accordance with the standard JB / T 10696.9-2011, using the group method or the knockdown method. The colony termite erosion rate is above Grade 2 according to the standard in Table 3. The knockdown termite erosion rate is in accordance with the Kt50min value of the sheath material in Appendix B of the standard.
