Safe solutions for electronic goods


Designed for producers of packaging films for the protection and shipping of semiconductors and electronic devices, AS-307 is a new permanent antistatic additive from Adeka.


“ESD can potentially damage finished products by rendering the circuits useless,” says Marie-Raphaël Morvillier, Technical Director at the company. “That is why ESD packaging, and films in particular, have become so valuable in today’s world, being designed to help prevent build-up of electrostatic charge both on the inside as well as on the outside. Different types of ESD films and trays

can now be found on the market based on their working principle - antistatic, conductive and/or dissipative.” Adeka’s AS-307, which was


consideration,” says Dr Annika Heinrich, Technical Development Manager at the Emery production site at Loxstedt, Germany. The Sukano additive compound has been tested


in PET lidding film applications, PET clam shells and thermoformed lids and trays where final parts were shredded, ground, washed and submitted to additional heating conditions to simulate recycling of a dedicated PET tray recycling stream according to the PETCORE TCEP protocol. Everglide is a PFAS-free processing aid from Mitsui Plastics in the US that is said to perform well when compared with traditional fluoro- materials. The company says that it allows film producers to achieve good melt processability, print adhesion, and a stable coefficient of friction over a broad temperature range, allowing faster speeds on lines.


Suitable for use with a variety of different polymers, the Everglide material offers both internal and external process aid benefits. Mitsui says it is a good alternative to fluoropolymer-based process aids with key benefits including reduced die pressure, extruder energy draw and apparent viscosity, which means process temperatures can be lowered. It has global compliance for food contact applications. As part of its move to meet the sustainability demands of its plastics additive customers, BASF now offers product carbon footprints (PCFs) for a

launched at K 2022, provides immediate and long-term antistatic performance for polyolefin films while maintaining good transparency. With a surface resistivity of 106 Ohms/sq, it can provide levels of antistatic performance from anti-dust to ESD. Available in pellet-form, it can be dosed into thermoplastics during melt- compounding and is suitable for use with the pink and blue pigments typically used to identify electrostatic packaging films. � www.adeka.eu


number of its antioxidant and light stabiliser products as a premium service within its Valeras portfolio. The company says that by improving CO2


customers in reaching their greenhouse gas emission reduction targets. Using its proprietary digital solution and


validated calculations, BASF says it can now provide cradle-to-gate PCFs. These include the total greenhouse gas emissions that occur from extraction of resources through the manufacturing of precursors to the making of the final chemical product itself. The first wave of available calculations includes


products from the Irganox, Tinuvin and Chimassorb portfolios. BASF says more products will follow.
