Paraformaldehyde plastic granules
Paraformaldehyde plastic raw materials can replace most non-ferrous metals, automobiles, machine tools, instrument internals, bearings, fasteners, gears, springs, pipes, conveyor belt accessories, electric water cookers, pump casings, drainers, faucets, etc.
1, Paraformaldehyde can be preheated during processing (about 80℃) without drying before processing, which is good for the dimensional stability of the product.
2, the processing temperature of Paraformaldehyde is very narrow (0～215℃), it will decompose when it stays in the barrel for a long time or the temperature exceeds 220℃, producing strong irritating formaldehyde gas.
3, the holding pressure of the Paraformaldehyde material should be relatively large (close to the injection pressure) to reduce the pressure drop. The screw speed should not be too high and the residual volume should be small.
4, Paraformaldehyde products have a large shrinkage rate, which is easy to shrink or deform. Paraformaldehyde has a large specific heat and a high mold temperature (80～100℃). The product is very hot when it is demolded. It is necessary to prevent burning fingers.
5, Paraformaldehyde should be molded and processed under the conditions of “medium pressure, medium speed, low material temperature, higher mold temperature”, and mold temperature control is required when precision products are molded.
6, with high mechanical strength and rigidity.
7, high fatigue strength.
8, good environmental resistance and organic solvent resistance.
9, strong resistance to repeated impact, good electrical properties, good recovery, self-lubricity, good wear resistance, and excellent dimensional stability.
