Quality Control

Junhua strictly implements ISO9001:2008 quality management system and strictly controls the quality of each batch of products. During the production process, operators conduct self-inspection, and QC personnel conduct random inspections and record them; after the products are completed, QC personnel conduct full inspection or random inspection of the entire batch of finished products, and provide customers with COA reports, size inspection reports and other inspection reports required by customers.

What are the high and low temperature resistance characteristics of PEEK

PEEK has excellent heat resistance and a melting point of up to 343°C. Since PEEK is a semi-solid thermoplastic, it can still maintain excellent mechanical properties near the melting point, which is very rare in plastics. At the same time, PEEK can withstand low temperatures for a long time and can be used as a component of liquid nitrogen equipment.

What are the corrosion resistance characteristics of PEEK

1. PEEK can tolerate almost any chemical except fuming concentrated sulfuric acid, and it can maintain good chemical stability even at higher temperatures. It has strong resistance to chemical corrosion and is usually used to manufacture parts that work in harsh environmental conditions or need to withstand frequent disinfection (such as chemical storage tanks and medical devices that need to be disinfected with strong oxidant hydrogen peroxide). 2. Although PEEK polymer has been widely regarded as a material that can withstand extremely strong chemical corrosion, of course, whether PEEK can withstand a certain corrosive medium is also related to the crystallinity of the PEEK parts, the residual internal stress, and the temperature and concentration of the medium in contact with…

What are the hydrolysis resistance characteristics of PEEK

Among all engineering plastics, PEEK has the best resistance to hot water and steam. PEEK polymer and its composite products (i.e., modified by glass fiber, carbon fiber, graphite, PTFE, etc.) can resist chemical damage caused by water or high-pressure steam, can be used continuously in hot water and high-pressure steam conditions, and still maintain good mechanical properties.
