The following six factors determine the high-performance plastics. (1) The type of polymer determines high-performance plastics The performance is also different because of the different polymer links, such as acetal resin (POM) impact strength, then the unsaturated polyester resin (UP) is more excellent. Even if the same material, structure, and polymerization degree are different, the performance varies significantly.

What Determines High-performance Plastics?
The following six factors determine the high-performance plastics.
(1) The type of polymer determines high-performance plastics
The performance is also different because of the different polymer links, such as acetal resin
(POM) impact strength, then the unsaturated polyester resin (UP) is more excellent. Even if the
same material, structure, and polymerization degree are different, the performance varies
significantly.
(2) Structure of polymers determines high-performance plastics
Although the polymer is made of repeated links, even the same links, if the connection method,
the degree of polymerization is different, the properties of the material are also different.
For example, if the polymer has branched chains, degree of cross-linking, molecular weight,
distribution, copolymerization mode, etc. All that will affect the nature of the material.
(3) Additives determines high-performance plastics
The type, quantity, and distribution of additives added to plasticizers, fillers, and stabilizers
significantly impact the physical properties of plastics, such as plasticizers used in plastics such as
polyvinyl chloride.
The impact of plasticizers is excellent, rigid polyvinyl chloride plasticizers containing less than 10%,
used as drainage pipes, etc.

Soft polyvinyl chloride containing 50% plasticizer can make transparent polyvinyl chloride
materials with 1/3 to 1/8 of the strength of rigid polyvinyl chloride.
(4) Molding method and molding conditions determines high-performance plastics
The injection molding method of plastics has a significant influence on the performance of the
material. The physical properties are different when the plastic injection molding method is
different. Such as cutting and processing of trial products, excellent performance.
While the mass production of products with injection molding, the product performance is
inferior. Even if the same molding method, molding conditions are different, the strength and
other properties may be different. Therefore, it is necessary to pay full attention to the drying of
resin particles before molding and the control of temperature, pressure, and molding period.
(5) Design of plastic parts determines high-performance plastics
To obtain high-performance plastics, the plastic parts themselves must have good structural
processability. The design of plastic parts varies according to the plastic molding method and the
performance of plastic varieties. A good or bad design can control the performance of the
products.
(6) Use conditions determine high-performance plastics
Due to moisture and water absorption deformation, the same material uses different conditions
and performance, such as urea-formaldehyde resin and nylon.
Plastics usually soften when the temperature rises and become brittle when the temperature
decreases. Plastics under stress will produce creep. Therefore it is necessary to choose the
material suitable for the conditions of use.
