Covestro has introduced a formable, textured polycarbonate film protects electronics components from damage. Makrofol SR906 7-2 polycarbonate film is capped with an acrylic layer, combining the strengths of acrylic – such as high scratch and chemical resistance – with the processing advantages of polycarbonate. “We formulated this film to meet an unmet need in the market,” said Chris Cooper, market development manager for speciality films at


Additives protect

airport roof BASF additives are helping to protect the roof at Incheon Airport’s Terminal 2 in South Korea. An additives package comprising a Tinuvin light stabiliser and Irgastab antioxidant helps protect roofing membranes made of thermoplastic polyolefin (TPO) sheet. The stabiliser uses BASF NOR-HALS technol- ogy. It has a lower interac- tion with system compo- nents and acidic

contaminants than other HALS, to help the membranes retain their mechanical properties. John Yu, director of

R&D at the membrane producer, Wonpoong, said: “Now we can ensure the polymer’s UV resist- ance and provide our customers with more durable products.” �

Covestro LLC. “This textured film offers excellent graphics capabilities and is versatile enough for a variety of appliance, automotive, consumer and industrial applications.”

Other benefits include: a velvet

matte textured UV resistant surface; a fine matte polycarbonate back surface for enhanced printability; and, the ability to hide sink marks. Industrial electronics company

Grayhill is using the film to create in-mould electronics for industrial


ExxonMobil launches flexible PE grades for packaging

ExxonMobil introduced two new polyethylene (PE) polymers for flexible packaging applications at the recent Chinaplas 2019. Exceed 2012MA delivers high sealing and extrusion performance for high-integrity flexible packaging films. It can reduce energy use, lower per-unit packaging costs, and cut packaging material and food waste. During the show, several companies produced film containing the material. They were: Huashan Plastics Machinery (lamination packaging); Xinle Huabao Plastic Machinery (cast stretch packaging); and Jinming Machinery (barrier packaging).

At the same time, the company introduced its Exceed 0015XC – for coating layers used in laminates – which claims

controls. DuraTech Industries, a full-service manufacturer of custom graphics, overlays, appliques and pressure-sensitive products, worked with Grayhill to produce the interface. The company converts the film, prints the decorative and functional conductive silver inks, project manages the forming and injection moulding, then ships the parts to Grayhill – which incorporates the component into its industrial products. �

high sealing performance, a broad hot-tack window and good processing. It offers easy extrusion onto substrates such as board and paper, aluminium foil, flexible films and PE-based woven fabrics. It is aimed at a range of applications including drink cartons, flexible packaging and tarpaulins. Hosokawa Alpine and

Dalian Totani also

demonstrated PE laminated stand-up pouches using the company’s Exceed XP grade.

“By working together, we can help customers create differentiated packaging solutions that offer

enhanced performance and processing,” said David Hergenrether, vice president of polyethylene at ExxonMobil. �
