Additive function of PVC plastic granules

2023-12-23 11:19

The additives used in the production of modified PVC plastics mainly include thermal stability system, impact modifier, lubrication system, processing modifier, filler and so on. Among them, the choice of thermal stabilization system should be based on the requirements of actual production, and more attention should be paid to the synergistic effect and confrontation effect between thermal stabilizers. Impact modifiers generally choose CPE and ACR impact modifiers, according to other ingredients in the production formula and extruder plasticizing capacity, appropriate addition of 8-12 copies can be, of which CPE sources are extensive, low price, ACR welding angle strength and aging resistance is higher.

The lubrication system can reduce the load of the processing machinery and make the product smooth, but excessive amount will cause the weld angle strength to decrease. Processing modifier can help improve the quality of plasticization, the appearance of the product has a certain improvement effect, 1-2 can be. The filler can help reduce the cost and increase the rigidity of the profile, but it has a greater impact on the low-temperature impact strength, so choose the active light calcium carbonate with higher fineness, 5-15 parts.

The temperature in summer is very high, similar phenomena have happened many times, and there will be power outages at home every once in a while, because of the previous situation. If we replace the insulating material with modified PC plastic, there will be no similar phenomenon, because the insulation performance will not be lost under strong temperature changes. It can also be said that if the temperature changes sharply, the insulation performance of the material will not decrease.

Insulating materials can also lead to loss of performance under changes in humidity, which is not the case when choosing to modify PC plastic manufacturing products. Just said that the insulation material because the temperature is too high and the combustion phenomenon, in fact, this kind of situation relative to the general insulation material once encountered extremely high temperature will inevitably burn, many people in daily life have encountered this kind of situation, in fact, the reason is because the material in preventing combustion performance is not strong enough.
