Zhongchu – Zhong Chu

Distributor: Product Supply (Form Board)

Committed to sustainable foaming technology

Overview & Milestones

Established in March 2019, focusing on the development of high-performance & light-weight polymer foaming technology.

Up to now, 150 employees, over 20,000 square meters facilities, 60 million RMB of actual capital utilized; 9 polymer microcellular foam production lines with capacity of 2500 sheets/day (by May-2023).

Core equipment and key foaming technology are independently developed with own IP. 12 invention patents ; R&D center & analysis and testing center.

Unique advantage – IP (Process & Equipment)

•Various Patents（more than 20 patents), including PCT patent, applied across the foaming process, machinery and tooling.

•FTO (Freedom To Operate) assessment obtained from the law firm without infringement, against the patent existed in the key regions globally.

Technical Route Map

Utilize clean supercritical microcellular foaming technology to realize the lightweight of high-performance elastomers, general-purpose polymers and special polymers.

Endowing foams with excellent mechanical, thermal, electromagnetic, acoustic and optical properties, Zhongchu has foams of plates, beads, block foaming, foam rolls and so on.

The thermoplastic non-crosslinked products route covers all consumer products and general industrial products, in order to ensure the recyclability and recycling of materials.

Cross-linked foams are only available for products with demanding and complex application requirements.

Carbon footprints – CO₂(N₂)

•CO2 is captured, cleaned and compressed from waste products of chemicals production by Linde AG

•No extra CO2 is produced in Zhongchu foaming process .

Typical Foaming Polymers

M-TPU
Aliphatic TPU (A-TPU)
M-TPEE
M-PEBAX(Bio-Based)

The micro-structural phase separation of hard segment and soft segment contributed to the high performance

Hard segment (HS) domains diffuse in a soft segment (SS) matrix.

Value-added Solution

Physical & Supercritical foaming

High energy return, lightweight and long-lasting cushioning.

No smell, no additional chemicals, foamed by N₂/CO₂.

No crosslinking enables recyclability

Bio-based version is also available, Content up to 44%
