Mayzo buys Bio Accutech

Mayzo, a US-based manufacturer and distribu- tor of polymer additives and speciality chemicals, has acquired Bio Accutech, a distributor of chemicals for the coatings, inks and plastics markets also based in the US.

Mayzo said the move

extends its global supply chain and adds several new optical brighteners, photoinitiators and PVC additives to its portfolio. This includes antioxidants, UV absorbers, optical brighteners, release coatings, polymer enhanc- ers, masterbatches and blends. Integration of the

acquired business has already taken place and all activities are now man- aged through Mayzo’s recently built 5,700 m2 operations centre at Walterboro in South Carolina. �

EU calls for more limits on bisphenol-A content

The European Chemicals Agency (ECHA) has opened a call for evidence following a proposal from Germany to place a restriction on the presence of bisphenol-A (BPA) and alternatives as an additive or unreacted monomer in articles and mixtures at levels or more than 0.02wt%. BPA is used as a monomer

in production of polycarbon- ate (PC) and epoxy resins. It is classified in the EU as toxic to human reproduction and restrictions already apply in certain end use applications. Germany says it wants to reduce environmental emissions of BPA and is taking the restriction route, rather than authorisation, as the latter does not effectively address imported articles. PlasticsEurope, which

represents PC producers at an EU level, said the German move was unexpected “considering the data already available on the

sources of BPA emissions into the environment, and further clarifying research results being on the way.” The association said studies shared with the German competent authori- ties show PC articles account for less than 1% of total BPA emissions to the environment. It said that it would contribute to the process with “the expecta- tion that a restriction proposal shall be based on facts and the most recent scientific insights.” Previous published studies indicate residual

Proposal from Germany

would impose a 0.02wt% limit on BPA

BPA content in PC is below the proposal’s 0.02wt% limit. n A pilot project carried out by ECHA’s Enforcement Forum has found more than 23% of products imported into the EU non-compliant with REACH and CLP Regulations. Inspectors across 16 member states checked around 1,400 products. 17% of the 1,225 checked for restricted substances had amounts above the required limit. Of the 167 products checked for CLP compliance, 64% were found to be non-compliant. �

Casio connects with Ultramid Advanced BASF Ultramid PPA is used in Casio’s latest G-Shock smart watch 12 COMPOUNDING WORLD | November 2020

Casio Computer Company is using BASF’s Ultramid Advanced N PPA in its newest digital watch and fitness tracker, the G-Shock GBD-H1000. The material is used in the terminal header, which sits on the terminal block and contributes to power charging and data synchronisation. The terminal header is about 1.2cm wide with a wall thickness of 0.2 mm and weighs less than 0.1 gram. Block and header are fixed to the motherboard using SMT (surface mount technology), which calls for

resistance to heat distortion tempera- tures of up to 260°C during the production process. Casio and BASF worked with Taiwanese connector maker Aces Electronics on the development. Ultramid Advanced N is said to combine high heat resistance, good mechanical and dimensional stability, low moisture uptake, high heat deflection temperature, exceptional chemical resistance and good adhesion to the metal terminal block �
