Why does Guolan have no chemical odor during the injection molding process?

- Aug 05, 2017-

In the highly competitive plastics market, irritating scents will make sales hampered, neutral or pleasant smell will be welcomed by customers. Therefore, the choice of an environmentally qualified plastic mold manufacturers to work is a major problem you should consider, although the use of odor removal technology may increase the cost of plastic products in the short term, but in the long term there will be a good return.


        We all know that plastic mold manufacturers in the injection process of many compounds have an unpleasant odor, including amines, phenol, thiols, peroxide, benzene, aldehydes, ketones, there are some plasticizers and flame retardants. Plastic used in the process of solvent will also release a strong chemical odor.


        Guolan's plastic processing products will be unpleasant odor, in order to overcome this problem to meet customer needs, general manager and manufacturers of managers who have long been committed to reducing the smell of these divergence levels. A typical solution to this problem is the use of high-grade environmentally friendly raw materials such as "Bayer", etc., with low-odor alternatives to replace those unpleasant additives, reduce the amount of residual monomer in plastic, add plastic adsorbent in the plastic And the addition of antibacterial agents to prevent the occurrence of those due to the role of bacteria and fungi and some unpleasant odor, as well as in the recovery of plastic processing can be solvent extraction and exhaust to reduce the residual odor.

Now the general mold manufacturers in the production process used in the catalyst of tertiary amines often bring a strong smell, but also on the car window will be fog. Guolan two-color mold manufacturers to solve this problem is to find these amines alternatives. One of the measures is the use of polyhydroxy compounds, polyhydroxy compounds are not only the composition of the polyurethane molecular chain, but also the same catalytic activity. Some polyhydroxy compounds can even replace half of the tertiary amine catalyst, so that the resulting product emits a much weaker odor.

        In addition, Guolan has also encountered in the PVC extrusion or calendering process used in the phenolic stabilizer is often replaced by low odor zinc stabilizer. Heat stabilizer tin octylate is also used in automotive PVC products because of its low odor and low atomization properties. Plant extracts such as erucic acid and oleic acid are much smaller than the odor of amine lubricants (for polyolefin and styrenic food packaging) made from animal extracts.
