Introduction
EPchem® POHF-0701 is polyolefin based material containing inorganic flame retardant, antioxidant, lubricant, etc., produced by mixing, plasticizing and then pelletizing. It is particularly suitable for sheath of communication cables, optical cables and so on.
POHF-0701 is excellent in mechanical properties, flame retardant performance, resistance to UV, good processability.

*The data in the list above is typical value rather than the guarantee value.

Processing
POHF-0701 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.
POHF-0701 can be extruded by squeeze die but also squeeze tube die.
POHF-0701 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.

Lamp Holders And Lamp Bases

We supply various Lamp Holders And Lamp Bases, including B22 Lamp Base, E27 Light Holder, Lamp Holder E27 B22 2 in 1, Straight Lampholder, Angle Lampholder etc.


The below information will help you to know more about Lamp Holders And Lamp Bases.

Lamp holders, also known as light sockets, are fixtures used in lighting installations. They hold a bulb whilst also providing an electrical connection to it. It is essentially a connection between the wire and the bulb. Some lamp holders also provide support for a pendant or lampshade.

Which material is used for lamp holder?

The lamp holder is generally divided into plastic lamp holder, bakelite lamp holder, ceramic lamp holder and metal lamp holder etc.

What is the difference between E14 and E27?

E14 is a 14 mm wide thin screw lamp holder. E27, on the other hand, is a 27 mm wide, thick screwed lamp holder. You can find out what type of bulb you need by measuring the lamp holder width.

There are many light bulb base sizes available.

C7 / E12 / Candelabra Base Bulbs ... typically used for chandelier-type fixtures and decorative lighting.

C9 / E17 / Intermediate Base Bulbs ... historically known as the old Christmas light bulb size.

Medium / E26 Bulbs (E27 in Europe) ... the same size as a standard household bulb.
