Degradable Plastic
As one of the key points in the development of light industry, the plastic industry has an annual production of millions of tons, and engineering plastics are also widely used in industrial fields, such as aerospace, machinery manufacturing, electronic appliances, automobiles, etc. At present, there are many plastic dryer manufacturers on the market, and a large part of them use the rotor as the core component to meet the dew point demand of plastic particles.

High Quality
 

 PLA and PBAT have strong water absorption contain a large number of active genes such as ester groups,carboxyl groups and hydroxyl groups,the degradable plastics deeply dried before use ensure the water content of biopolymer materials 0.02%~0.025%,whether in compound modification or molding process,otherwise that products Defects such as deterioration of physical properties occur(such as reduced impact strength and tear strength,and poor surface properties). 
In order to deal with the above-mentioned hydrophilic problems of plastic polymer materials,Puresci collects and analyzes the original physical parameters based on the water absorption and dehydration curves of different plastic particles,and then optimizes the logic control of the dehumidification and drying system.Customized engineering solutions to reduce energy consumption.

PET
 
Moisture easily hydrolyzes PET,and the increase of moisture increases the reverse reaction,making it difficult for PET become long chains.Controlling the moisture content during PET processing beneficial to improving the annual and quality of PET products.

PLA,PBAT
 
Because degradable plastics contain a large number of active genes such as ester groups,carboxyl groups and hydroxyl groups,under the attack of water molecules,chain scission reactions are very likely to occur,resulting in the decline of product performance.

Polyurethane elastomer
 
There are many hydrophilic groups in the molecular structure of the polyurethane elastomer particle,so once it is exposed to the air,it will cause moisture absorption.
4
TPU
 
Insufficiently dried TPU raw materials can easily lead to processing difficulties, bubbles or silver streaks, and generally need to be processed after dehumidification and drying.
