SABIC Introduces LNP™ ELCRES™ CXL Polycarbonate Copolymers
14.02.2025
SABIC has launched its new LNP™ ELCRES™ CXL polycarbonate (PC) copolymer resins, designed to offer exceptional chemical resistance. These materials aim to assist customers in the mobility, electronics, industrial, and infrastructure sectors in managing increased exposure to harsh chemicals that can lead to environmental stress cracking and premature component failure.
Addressing Industry Challenges
The heightened use of disinfectants and personal care products has increased chemical exposure for plastic parts. Maureen MacDonald-Stein, Director of Portfolio Strategy and Marketing at SABIC's Specialties business, noted, " Heightened concerns about cleanliness have persisted after the pandemic, prompting consumers to frequently disinfect surfaces from smartphone displays to EV charger handles. " She also highlighted the constant contact of electronics with skin oils and lotions due to the growing popularity of wearables and smartphones. These factors contribute to greater chemical exposure for plastic components.
The new copolymer resins offer several advantages:
- Enhanced Chemical Resistance: Surpassing traditional amorphous materials like standard PC resins and acrylonitrile-butadiene-styrene (ABS) blends.
- Durability: Excellent low-temperature impact resistance and weatherability, enhancing part longevity.
- Diverse Applications: Suitable for various industries, including mobility, electronics, industrial, and infrastructure.
Scott Fisher, General Manager of Technology at SABIC's Specialties business, stated, " Our proprietary copolymer technology rises to the challenge of protecting applications from damage and loss of value caused by these substances."
Sustainability Initiatives
SABIC also offers ISCC PLUS certified bio-renewable versions of these materials under the LNP™ ELCRIN™ CXL brand. These bio-based grades aim to reduce carbon dioxide emissions compared to traditional counterparts while delivering the same performance. They are part of SABIC’s TRUCIRCLE™ program, which focuses on helping companies achieve their sustainability goals.
SABIC's LNP™ ELCRES™ CXL PC copolymers are designed to meet the increasing demands for chemical resistance in various industries, aiming to enhance component durability and support sustainability efforts.
The new SABIC CXL portfolio offers a wide range of products, including opaque and transparent non-flame retardant (FR) grades, opaque, thin-wall FR grades and glass-reinforced options. These materials also deliver value-added features such as non-brominated/non-chlorinated FR at thin gauges, low-temperature ductility (down to -60oC), high flow for easy processing and good colorability to meet aesthetic requirements. They can meet both ultraviolet (UV) and water immersion requirements (f1 rating) for outdoor suitability under UL 746C.
