impact performance and strength to meet burst pressure test requirements in shower heads, faucets, valves, water meter internal components and other parts. It has 20-30% higher burst strength (80-81MPa) compared to its legacy counterpart (64-65 MPa).
It also boasts superior fatigue performance and
flexural and tensile modulus and is awaiting global drinking water certifications. The material is a non-reinforced, impact-modi- fied blend of polyphenylene ether (PPE) and polystyrene (PS). In addition to injection moulding, it can be extruded to produce pipes and profiles.

meet upcoming butadiene-free regulations
a mass production technology to make LCPs from a bio-derived monomer. LCPs have high heat- and fire-resistance and are used in a variety of electrical and electronic components. In the new manufacturing process, Sumitomo has adopted a ‘segregation approach’ that separates biomass materials from others during production. This enables precise control of the biomass content and can clarify how much is included in the product. It also uses the mass-bal- ance approach.
Sumitomo aims to begin supplying the product from 2027.
Butadiene-free Sabic says its new Noryl WM300G resin is aimed at water management applications, in anticipation of upcoming butadiene-free regulations. It delivers high impact resistance and hgh
strength without the use of traditional impact modifiers that can potentially release butadiene during processing or in use. Using the resin can help customers address
future regulatory restrictions while gaining im- proved properties compared to the incumbent Noryl 713S resin. “The new material offers a drop-in replacement for the incumbent resin and delivers improved properties, providing a seamless transition to the newest material technology,” said Sergi Monros, vice president of the specialities unit at Sabic Polymers. Noryl WM300G is formulated without conven- tional impact modifiers that can degrade under exposure to high moulding temperatures and long barrel residence times. The butadiene molecules released can leach into drinking water, potentially affecting human health. The new product improves processing stability to avoid butadiene release, while ensuring high

Part protection Sabic has also introduced LNP Thermocomp WFC061I, a non-brominated/non-chlorinated flame retardant (FR) grade of polybutylene terephthalate (PBT) that can be used in electric vehicle control units (EVCUs). The new material is suitable for the housing of these applications, providing good structural performance for protecting sensitive electronic parts from fire/smoke, impact, moisture and other threats. The compound can replace metal in EVCU covers to reduce weight and expand design freedom. Alternatively, it can replace polymers that use halogenated FRs, which can affect the environ- ment. Other advantages include colourability, low warpage to increase yield and high optical trans- mission for precision laser welding. Sabic says the glass fibre-reinforced compound is the world’s first laser-weldable FR PBT. The material provides the high optical transmis- sion (20% at 3mm thickness) for laser welding, which joins two plastic parts without adhesives, chemicals, fasteners or vibration. The laser energy passes through the material to the surface of the absorptive material, where it generates heat at the interface and melts the plastic. Its compatibility with laser welding helps manufacturers speed up and simplify assembly, says Sabic.
