- Dec 20, 2017-

In the purchase of injection molding parts, sometimes we meet the odor of the situation, which is not a small impact on the health of the user. So, how do we avoid the odor when we are doing the injection molding? Here we are simply to understand.

1, strictly control the use of additives

The catalyst of tertiary amine used polyurethane foam in the production process will bring a strong smell, will be in the car window on the fog, we can find these amine substitutes using hydroxyl compounds, polyhydroxy compounds is not only the polyurethane molecular chain component, but also has the same catalytic activity, some polyhydroxy compounds and can replace half of the tertiary amine catalyst, thus, injection molding products smell fade out.

2. Choose a more pure resin

A lot of plastic moulds, especially polyvinyl chloride, styrene, polyethyl acetate and acrylates, are smelled by smell. If odorless resin is selected, the effect is better.

3. Pay attention to the use of adsorbents

If a small number of zeolites are filled in polymer, the effect of data odour can be removed. Zeolite has many crystalline vaguely, which are able to catch small molecules with odor.
