Applications of EMS-Grivory Grilamid® L 20A HL NZ nat Nylon 12, Impact Modified, Conditioned in Industrial Manufacturing

EMS-Grivory Grilamid® L 20A HL NZ nat Nylon 12, impact modified and conditioned, serves in multiple industrial sectors requiring durable, high-performance polyamide resins. We supply this material for specialized downstream use cases where mechanical resilience, long-term flexibility, and chemical resistance are critical to the finished components.

1. Automotive Pneumatic Tubing and Connector Systems

Automotive OEMs and first-tier suppliers select this impact-modified PA12 grade for the production of assured pneumatic control lines, SCR (urea solution) transport hoses, and fluid couplers in both commercial and passenger vehicles. The consistent molecular structure and enhanced impact resistance ensure safety and reliability, even under high-flex cyclic conditions and subzero temperatures encountered during the vehicle lifecycle. Nylon 12 enters tube extrusion lines and injection molding processes after precise polymer drying and melt filtration to minimize microvoids—critical to maintaining burst and pressure cycling performance required by automotive validation laboratories.

2. Pipe Systems for Fuel and Chemical Transport

Industry contractors and system integrators use this grade for building chemical-resistant flexible pipes conveying light fuels, industrial chemicals, and compressed gases. Its modified impact and low moisture uptake make it suitable for secondary containment piping or flexible coupling segments where steel or rigid plastics fail to provide installation flexibility or corrosion resistance. After resin pre-conditioning, the polymer feeds directly into corrugated or multiwall pipe extrusion tools. Manufacturers apply precise die temperatures and calibration baths to control wall thickness and elongation, reformulating with antistatic or flame-retardant additives if specified under project specifications.

Industry compliance standards

• EN ISO 21012 for Thermoplastic Pipes and Fittings (Industrial Applications)
• ASTM D2513 for Thermoplastic Gas Pipes
• REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals, EU regulation)

Typical usage ratio

• Applied at 70–100% in single- or multi-layer chemical pipe; may be co-extruded with 10–30% barrier layers such as PA6/12 blends, EVOH, or PVDF as required by permeation tests.

Downstream process integration

• Granulate drying and melt filtration
• Feedstock into pipe extrusion and calibration baths
• Inline welding, bending, or fitting assembly during manufacturing
• Online stripping, cutting, and quality testing before shipment

Final product types

• Flexible gasoline and diesel fuel lines
• Chemical transfer piping for industrial plants
• Compressed air and specialty gas transport pipes
• Flexible chemical-resistant conduit solutions

3. E&E (Electrical and Electronic) Cable Gland and Connector Components

Electrical equipment manufacturers incorporate this impact-modified Nylon 12 for over-molded glands, precision bushings, and terminal housings where repeated flexing, vibration, and exposure to heat-cycling threaten part integrity. The resin’s low dielectric constant and superior insulating properties enable safe use in demanding industrial control cabinets, outdoor LED modules, and cable routing components in utility-grade installations. We supply precision pelletized forms that integrate efficiently into automated injection molding equipment. Process engineers monitor cavity fill and hold times to minimize internal stress formation that could otherwise result in assembly failures or field issues under prolonged loading.

Industry compliance standards

• IEC 60216 (Electrical Insulating Materials – Thermal Endurance)
• UL 94 HB/V2 for Flammability
• RoHS Directive 2011/65/EU and amendments

Downstream process integration

• Automatic pellet feed into multi-cavity injection molds
• In-mold labeling or insert-molding for integrated metal contacts
• Post-mold annealing for stress relief
• End-of-line electrical isolation and resistance checks
