PET sheets achieve a better balance of transparency and strength.

Through repeated experimentation, researchers have developed an improved formulation for PET sheets. By incorporating a specific proportion of nano‑scale additives into the raw material and employing a unique blending and stirring process, these additives are uniformly dispersed throughout the PET molecular structure. This not only enhances the transparency of the PET sheets, achieving a light transmittance of over 92%—approaching optical‑grade standards—but also boosts their tensile strength, increasing it by 20% compared with conventional PET sheets. This breakthrough offers a new option for high‑end applications such as premium packaging and optical displays, where PET sheet performance requirements are particularly stringent.

Key progress has been made in the self-healing technology of PE protective films.

A research team has successfully developed a self‑healing polyethylene (PE) protective film. When the surface sustains minor damage such as scratches, the film can autonomously reorganize and repair the affected area under specific temperature conditions, thanks to a unique internal chemical molecular mechanism. The researchers incorporated polymers containing dynamic chemical bonds into the film material; upon damage, the broken bonds are re‑formed in response to thermal stimulation, enabling rapid self‑repair. Currently, this technology has completed laboratory validation and is expected to enter industrial production soon, bringing significant benefits to industries—such as electronics and automotive—that require long‑term surface protection.

Significant breakthrough achieved in the flame-retardant performance of PVC sheets.

After extensive research and development, a new type of flame‑retardant PVC sheet has been introduced. By incorporating an innovative flame‑retardant additive system into the conventional PVC formulation—comprising multiple synergistic flame‑retardant elements—the material can rapidly form a dense char layer at high temperatures, effectively blocking heat transfer and oxygen ingress to suppress combustion. Testing has demonstrated that the new PVC sheet achieves a UL 94 V‑0 rating, significantly exceeding that of standard PVC sheets. This breakthrough holds substantial significance for industries such as construction and electrical engineering, where fire safety is paramount, and will markedly enhance the safety of related products.

PET sheet biodegradability technology has achieved a milestone.

As environmental protection requirements continue to tighten, the development of biodegradable technologies for PET sheets has become a major research focus. Recently, researchers have successfully engineered biodegradable PET sheets by modifying the polymer’s molecular structure and incorporating biodegradable segments. In natural environments, these sheets can gradually break down under microbial action, significantly shortening their degradation timeline. At present, biodegradable PET sheets are undergoing small-scale trials in certain food‑packaging applications, with promising results. They hold great potential to replace conventional non‑biodegradable PET sheets on a large scale, helping to mitigate plastic pollution.

Release of Technology for Optimizing the Antistatic Performance of PE Protective Film

To address the issue of electrostatic charge‑induced dust adhesion and interference with electronic device operation in applications such as the electronics industry, a new antistatic optimization technology has been introduced. This technology incorporates a specialized antistatic agent during the PE protective film manufacturing process and employs an advanced blending technique to ensure uniform distribution of the agent throughout the film, thereby establishing a stable conductive network. Testing demonstrates that PE protective films produced using this technology exhibit a significant reduction in surface resistivity, with static decay times shortened to one‑tenth of their original values. This effectively mitigates electrostatic hazards and enhances the stability of electronic devices during manufacturing, storage, and other stages.
