Introduction
EPchem® POHF-0702 is polyolefin based material containing inorganic flame retardant, antioxidant, lubricant, etc., produced by mixing, plasticizing and then pelletizing. POHF-0702 is appropriate for sheath of power cables, control cables, communication cables and so on.
POHF-0702 is excellent in mechanical properties, flame retardant performance (cables can pass mounted bunched wires or cables-Category C), low smoke, outstanding resistance to cracking and high temperature, good processability.

*The data in the list above is typical value rather than the guarantee value.
Processing
POHF-0702 has good processing performance, can be well processed using PVC and Polyethylene standard extrusion screw, preferring a low compression ratio (1.2 ~ 1.8) screw for the best extrusion effect. In general we recommend the following processing conditions:
  • Extruder L/D: 20~25
  • Filter (mesh): 30~60
  • Temperature setting:
     Zone1    Zone2    Zone3   Zone4    Zone5      Die
    110ºC   120ºC   135ºC  145ºC   150ºC   150~165ºC
The above temperatures are for reference only, but should be adjusted depending on specific equipment. But the melting temperature should not exceed 170ºC.
POHF-0702 includes black and natural color. Users are free to add color masterbatches to natural color material. The suggested weight ratio is 1.5% or so.

Storage
These compounds must be stored under the following conditions:
  1. closed and undamaged bags
  2. ambient temperature does not exceed 45ºC
  3. avoid direct exposure to sunlight and weathering
  4. shelf life:12 months.
Package
To be packed in aluminum foil bag inside and kraft paper bags outside, 25kg net each; or damp-proof cabinets on pallet, 1000kg net each.

Led Strips

We supply various LED strips and Led Strips Driver, including 5730, 2835 and 5050 Outdoor LED strip lights.

The below information will help you to know more about LED strips..

Do LED light strips have to be plugged in?

The first thing we should note about these lights is that all electricity needs to have an outlet to work correctly. So yes, led strip lights do need to be plugged in. They also require some power source like batteries or solar panels, meaning there's no way around using electricity either way!

Can LED strips be cut?

LED light strips are favored for their versatility and flexibility - particularly since they can be cut to fit different areas of your home. Whether you want to add extra illumination to your kitchen counters or a backlight for your TV, LED strips can be trimmed to fit your needs and space.

Why do LED strips fail?

Bad Pin Connection – If your LED strip light fails to turn on at all, then check your pin connections. Most likely, the pin is not inserted correctly. In rare cases, the pin is faulty. These tiny connectors are rather delicate items so you have to be very careful when inserting them.
