As4 H12
semiconductor· As4 H12
AS4 H12 is a carbon fiber composite material, specifically an epoxy-matrix composite reinforced with AS4 carbon fibers in a unidirectional or woven configuration. This material is widely used in aerospace, automotive, and sporting goods industries where high specific strength and stiffness-to-weight ratios are critical, offering a cost-effective balance between performance and manufacturability compared to higher-grade carbon fiber systems.

Quality & Standards
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
