Selection of plastic modification formula

Formula machinability that modified plastic formula has machinability, is to meet the

requirements of plastic molding products after modification. For the main manifestation of

the formula processability: The heat resistance of the additive is good, no evaporation loss

and decomposition deactivation, and the formulation has little wear and corrosion to the

equipment and no toxic gas release, which can be used as the evaluation standard.

1. Fluidity of the modified plastic

The fluidity of plastics is the main aspect that affects the processing performance of plastics,

and is also the important basis for choosing which plastic processing method to use. In

general, the addition of inorganic fillers will lead to the decrease of flow properties, which

needs to be optimized by adding flow modification. Common organic auxiliaries include

decabromodiphenyl ether and tetrabromobisphenol A.

2. Heat resistance

Heat resistance is considered in two ways:(1) Reduce the processing temperature of resin,

processing temperature does not exceed the decomposition temperature of additives, to

ensure the stable existence of additives, reflecting the modified performance; (2) The

addition of a certain amount of antioxidant additives prevents thermal decomposition and

affects the properties of the resin. In general, most organic dyes decomposition temperature

is low, not suitable for high-temperature processing of engineering plastics;The

decomposition temperature of spices are low, generally below 150 °C, can only be used for

low processing temperature of EVA resin carrier.

3. Environmentally friendly properties of the formulation

Environmentally friendly formulations include: harmless to human body, equipment,

environment and users. Human hygiene-resins and additives of choice should be absolutely

non-toxic or within specified limits. Pollution of the environment-the selected component

can not pollute the environment.

4. Cost Price and source

The plastic modification formula pursues the price to be lower the better, in the

implementation process regarding the auxiliary use the following principle:

(1) Preferential use of low-cost raw materials;

(2) Preferred use of existing raw materials: no procurement, stable source, clear

performance;

(3) Preferential use of domestic raw materials: price fluctuations by foreign exchange, trade

policy and other small impact;

(4) Preferential use of nearby raw materials: reduce the cost of inventory;

(5) Preferential use of general raw materials: a wide range of sources, relatively stable

performance.
