Thermoplastics offer the potential to build cleaner, safer and more cost-effective water systems; however, each material must first undergo extensive testing. Materials research, testing and evaluation at SABIC’s Fluid Centre of Excellence are leading to new fluid engineering innovations. These include the use of Noryl polyphenylene oxide (PPO) resin in water valves to provide better hot water resistance than other resins and greater design freedom and part integration than metal. Noryl and Noryl GTX resins are also used widely in water meter components and pump impellers, due to their low water absorption and dimensional stability that provide better accuracy and performance.
Noryl PPX630 resin can be typically used for new generations of environmentally compliant condensing heat exchangers for boiler systems. Noryl PPX resin is commonly used by customers for several criteria: good heat resistance, remarkable chemical resistance to condensing fluids and fumes and very good mechanical resistance and dimensional stability. Noryl resin is typically used for manufacturing the housings that contains the stainless steel coils. Components moulded with Noryl PPX630 resin can allow easy assembly of the condensing heat exchanger on automated production lines. This not only brings a second potential cost saving but may also offer the advantage of ease of integration relative to this industry.
LNP Lubricomp graphite-filled compounds are a good candidate for typical applications such as water meter pistons due to their abrasion and wear resistance, hydrolytic and dimensional stability, and low coefficient of friction.
Ultem resin is typically used for highly technical applications requiring high temperature, tight dimension and long term stability in combination with potable water approvals.
Proven materials and new innovations
SABIC is supporting Polish packaging customers with its linear low density polyethylene (LLDPE), low density polyethylene (LDPE) and high density polyethylene (HDPE) grades for blown film and cast stretch film.
Recently, the company unveiled a combined polyethylene (LDPE/LLDPE/HDPE) multi-layer film concept of up to five layers for typical food and household products packaging. These film combinations allow manufacturers to create unique property configurations that can be used for specific needs of brand owners as well as the demands of the consumer. Multilayer film offers down-gauging opportunities that can reduce material consumption for cost savings. The concept also optimizes equipment performance for higher processing speeds and lower energy consumption.
