When polypropylene is molded as housing of electronic appliances (Electric jar, Coffee maker, Flyer..) which generate electric heat, there are applied mineral-filled polypropylene (PP compound) which was improved heat stability but decreased surface appearance because of that filler chemical ingredients and structural properties. If you use our high glossy masterbatch, you can solve these problems, so you can acquire the molded articles which have high heat stability and high glossy surface.

During molding process, PP compound is convenient to use because of simplicity to deliver raw material but there are some troubles with uneven quality and high cost in raw materials, and if our masterbatch is applied in production, you can achieve the molded articles with uniform & superior quality and have cost reduction in your application.

Filler Content : 60 ~ 80 wt%
Carrier resins : Polypropylene, Polyamide
