Polyformaldehyde in the application process usually has the double advantage of performance and cost, so that the balance of material selection is inclined to polyformaldehyde. The following is an inventory of some products that can be replaced by polyformaldehyde.

1. Polyester

Polyformaldehyde performs better than PBT in some typical PBT applications (based on better heat resistance and resistance), where its electrical properties are sufficient and the cost advantage becomes apparent.

In premium car applications, the cost difference is 20%. Therefore, in the competition between PBT and enhanced polyamide, polycarbonate and polyformaldehyde in the field of automobile manufacturing, the situation of polyformaldehyde encroaching on its market often occurs.

2. Polycarbonate

PC in the automotive industry in internal and external decorative parts of the use of a long history, but the inherent performance of polyformaldehyde plus related new technology to bring the possibility of cost difference, so that in the category of internal and external decorative parts instead of a large number of PC structure. PC plate extrusion line is mainly used in automotive industry, film switch of electronics, LCD for computer, mobile, sunglasses, helmet, special printing, medicine packing and so on.

3. Polyamide

Polyamide varieties, early application, industrial application basis is good. But polyformaldehyde has the potential to replace nylon in many applications, where it is superior in a range of properties.

The use of reinforced paraformaldehyde instead of nylon in the intake manifold was spearheaded by BMW and Ford, and other components in the engine category have followed suit. Once successful, it is estimated that there is a 30% cost advantage.

4. Polyphenylene sulfide

PPS reflects its overall advantages with other general engineering plastics, but in the actual application field, the gap between the comprehensive performance and polyformaldehyde, as well as the advantages of polyformaldehyde itself, so that polyformaldehyde has a good opportunity to enter the application field usually occupied by PPS.

5. Polytetrafluoroethylene

Its friction and wear properties and resistance to fatigue and creep make it possible to replace PTFE in many applications.
