Urea Moulding Compound (household appliances or dinnerware)

Product Overview

Description

 

Main application: household appliances or handles.

 

Appearance: powder or granule

 

1. Features and applications

 

UF1P-A series of products are powdery urea moulding compound, which are made by using urea formaldehyde resin as the base material, cellulose as the padding, and adding lubricant, curing agents, pigment and other additives. UF1P-A series of products are suitable for molding such household appliances as tableware, mahjong pieces, ashtrays, and flower pots.

 

UF1G-A series of products adopt UF1P-A which has undergone the hot-granulation process. This granular moulding compound has the features of low amount of volatile matter and easy exhaust, suitable for moulding or automatically self-feedings moulding method, Bottle caps, handles,

 

UF1I-A series of products use UF1P-A which has processed by hot-granulation process. This granular injection moulding compound has smooth and fine surface as well as well-distributed color, with high production efficiency and stable performance. It is suitable for manufacturing various handles and household appliances which have to go through complex and difficult moulding manufacturing and hard mould pressing process.
