Any unit holding the "Gold Mine Approval Certificate" or "Golden Minerals Quasi-Certificate" shall be replaced by the "Golden Minerals Approval" issued by the Gold Economic Administration of the State Economic and Trade Commission before the end of 2000 .

POM/Acetals/Derlin Plastic Rod

POM plastics ,lalso named Acetals(paraformaldehyde) (semel - Stirling),

English name: Polyoxymethylene (Polyformaldehyde),POM mainly has antistatic POM, conductive POM,POM+PTFE SHEET.

POM plastics (polyformaldehyde resin) definition: polyformaldehyde is a linear polymer with no side chain, high density and high crystallographic properties.

According to the different chemical structures in the molecular chain, there are two kinds of homoformaldehyde and copolymerization.

One of the synthetic resin, also known as polyformaldehyde resin, POM plastic, and steel, etc.

POM/Acetals Plastic is a kind of white or black plastic granule with high hardness, high steel and high abrasion resistance.

Mainly used for gears, bearings, auto parts, machine tools, instruments, etc.


Advantages:

1. Excellent abrasion and creep resistance property;

2. High dimensional and shape stability;

3. Retains toughness under low temperature (-40°C);

4. Resistant to organic solvents; Insoluble under normal temperature;

5. Thermal deformation temperature is close to that of PC plastic, PTFE plastic and nylon plastic;

6. High compressive strength, second only to Glass Fiber;

7. Good sliding property; wear resistant; non-water absorbent;

Disadvantages:

1. Not resistant to acids, especially to mineral acids;

2. Not resistant to UV;

3. Not self-extinguishing, and thus must be kept away from fire;

4. Not resistant to impact.

Applications:

1. Sliding parts: bearing and lining, roller, conveyor chain;

2. Precision mechanical components: gear, cam, coupler, idler roller;

3. Waterproof components: impeller, pump case, gasket;

4. Electrical parts: guide pulley, spring lock;

5. Fixture, lever, handle, knob and other jig materials.


Modified POM/Acetals Plastic

reinforced POM/Acetals Plastic

Main reinforced material such as glass fiber, glass or carbon fiber, and glass fiber is the most commonly used, the enhanced mechanical performance can be improved 2 ~ 3 times, heat distortion temperature increased by more than 50 ℃.

High lubrication POM POM/Acetals Plastic

In POM, graphite, F4, molybdenum disulfide, lubricating oil and low molecular weight PE are added to improve the lubrication performance

Combustion characteristics: easy to burn, continue to burn after fire, the upper end of the flame is yellow, the lower end is blue, and the melting drop, the strong irritating formaldehyde flavor, the fish smell

Specification: the thickness of sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of 10-180mm is 600*1200mm.

POM/Acetals Plastic can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.and The diameter of the rod can be produced from 2mm to 250mm, the length is 1 meter, and POM/Acetals Plastic can be ordered to be more than 3 meters in length.
Color: Black ,white beige and brown, can also be made another color, and the color order is 500KG.


Modified varieties: can be added to the glass fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.
Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
