Conductive additive for glass fiber filled polyamide compounds with maintained mechanical properties and required processability

TUBALL™ MATRIX 808형태의 TUBALL™ 그래핀 나노튜브는 폴리올 에스테르 캐리어 기반의 다목적 전도성 첨가제입니다. 열가소성 재료에 우수한 전기 전도성을 제공하는 동시에 기계적 특성을 유지하고 유리 섬유 충전 화합물의 MFI 레벨을 유지하도록 특별히 설계되었습니다.

기존의 첨가제와는 달리 TUBALL™ 그래핀 나노튜브는 극소량의 첨가량으로 인하여 충격강도를 유지하며, 높은 MFI레벨로 복잡한 구조의 사출물을 가능하게 하는 등 부가적인 가치를 구현할 수 있습니다. 이는 유리섬유와 MWCNT, 또는  카본블랙 컴파운드로는 구현이 어려웠습니다. 

CONDUCTIVE ADDITIVES FOR GLASS FIBER FILLED PA: TRADITIONAL VS TUBALL™

Note. This diagram is based on an average trends compared with other additives based on OCSiAl data. Product performance may vary depending on product type and formulation.

Benefits provided by TUBALL™ nanotubes for GF-filled PA:

• Ultra-low dosage starting from just 0.05 wt.% TUBALL™ graphene nanotubes*
• Maintains good balance of mechanical properties
• Enables a new combination of GF-filled PA properties in comparison to standard conductive agents 
• Permanent, stable and uniform electrical resistivity without “hot spots”
• Stable performance reducing the number of out-of-spec parts
• Good processability and easy handling
• Allows production of conductive parts that retain colors

*Dosages may vary depending on the formulation, processing, and products.

30% glass fiber filled polyamide compounds. Injection molded samples. Surface resistivity: ASTM D257. Volume resistivity: ASTM D4496.

EASY TO APPLY WITH STANDARD EQUIPMENT

TUBALL™ MATRIX can be processed with standard equipment widely used in the thermoplastics industry. 

PA enhanced with TUBALL™ graphene nanotubes has found wide usage in the automotive e-painting, automotive safety, ESD materials and ATEX applications.
