With a total of 152,134 visitors attending, the four-day CHINAPLAS 2021 was successfully held from 13 - 16 Apr in Shenzhen, China. There were countless new technologies and product solutions for the plastics and rubber industries showcased at the trade fair.


CHINAPLAS 2021 was successfully concluded at high note.

As a review of CHINAPLAS 2021, CPRJ concludes five major development trends reflected out of such many exhibits and on-site interviews.


Sustainable materials for facilitation of circular economy


The plastics industry is undergoing a transformation to meet the targets of “carbon neutrality”, “emission peak” and different regulations related to plastics. Therefore, numerous sustainable material solutions were brought out at the exhibition.


SABIC, a global leader in diversified chemicals, presented a series of high-performance material solutions in packaging, automotive, building & construction, healthcare, and consumer goods.


SABIC introduced the lenses of sunglasses made from LEXAN PC.

Especially, SABIC has partnered with eyewear lens leader POLYRAY to apply its certified renewable feedstock-based LEXAN polycarbonate (PC) resin, part of SABIC TRUCIRCLE portfolio and services for lenses of sunglasses, safety glasses, and sports goggles.


Covestro announced that it will launch a novel zero carbon footprint polycarbonate within this year as an important step towards a circular economy. It is reported that the Makrolon polycarbonate products are made from alternative raw materials and by renewable energy.

ZYSJ Medical, a service provider of medical polymer solutions, focuses on the medical plastic industry for several years. The company distributes various medical-grade polymers imported from Japan, South Korea and other places, and develops customized medical-grade materials.


The Vivion cyclic block copolymer delivered by ZYSJ Medical has the characteristics of high purity and high transparency.

Arburg illustrated a fully automated manufacturing system for pipette tips. An Allrounder 470 H with a clamping force of 1,000 kN uses a hot runner mold to produce 48 pipette tips in a cycle time of approximately six seconds.

5G leads to improvement of materials and processes

In the future, 5G, new energy, photovoltaic and high-performance packaging materials will be having irreplaceable technical advantages.


JCtimes Group has been working on technical research in the field of multi-layer co-extrusion, and attaches great importance to simulation analysis research and big data integration from material sources.


Liang Bin, President of JCtimes Group.

According to Liang Bin, President of JCtimes Group, the new 2.5D multi-layer co-extrusion algorithm means that through the real analysis calculation of the film series multi-layer composite, it achieves precise analysis which was difficult to be done by the traditional method.

Kingfa showed a series of high-performance material solutions for weight reduction, wave transmission, and weather resistance to help shape 5G smart life, including: applications for 5G base station vibrators, AAU radomes, RRU radomes, optical fiber subframes, antenna covers and other key components materials.
