Applications of EMS-Griltech Grilamid® DM 10 Nylon 12 Monofilament in Industrial Manufacturing

As the original manufacturer of EMS-Griltech Grilamid® DM 10 Nylon 12 Monofilament, we focus on verified industrial applications where our material delivers unique performance and certified dependability. Below, we detail the principal downstream sectors and manufacturing settings where processors incorporate our monofilaments, with reference to regulated standards, industrial usage ratios, process roles, and the types of finished goods produced by our global business partners.

1. Automotive Fuel System Components

Automotive tier suppliers and OEMs rely on this nylon 12 monofilament for critical fuel line reinforcement, due to its stability in direct hydrocarbon contact and consistent behavior under thermal cycling. It enters production at the fiber reinforcement stage, providing dimensional accuracy and resistance to swelling, which is essential for long-term sealing and mechanical integrity within multilayer fuel pipes and hoses.

Industry compliance standards

• SAE J2260 (Nonmetallic Fuel System Tubing)
• ISO 7628 (Road Vehicles - Polyamide Tubing for Air Braking Systems)
• US EPA fuel permeation standards
• Automotive OEM material specifications (e.g., VW TL 52643V)

Typical usage ratio

• Typically 10-30% of the reinforcement by weight, depending on hose wall construction, diameter, and multilayer integration; engineers adjust ratios for burst strength and permeability targets in specific vehicle platforms.

Downstream process integration

• Combined with polyolefin or fluoropolymer layers during extrusion or co-extrusion; monofilaments are wound or embedded as part of the inner hose reinforcement before final extrusion and bonding steps.

Final product types

• Multilayer automotive fuel hoses
• Pressurized fuel pipes
• Flexible brake lines with PA12 reinforcement

2. Industrial Filtration Media

In specialty industrial filtration, such as fine-mesh screens for electronics, food processing, and water treatment, processors use this material for woven and knitted monofilament fabrics. Its extra-low extractables and chemical inertness make it popular for high-purity filtering where trace contamination is tightly controlled and long operating cycles are typical.

Industry compliance standards

• FDA 21 CFR 177.1500
• EU Regulation (EU) No. 10/2011 on plastic materials intended to contact food
• ISO 16889: Hydraulic fluid power filters
• NSF/ANSI 61: Drinking water system components

Typical usage ratio

• Monofilaments comprise 100% of the yarn matrix; mesh density (20–250 μm) and monofilament diameter (from 10% to 100% basis change) are chosen based on separation efficiency and required tensile properties.

Downstream process integration

• Woven or knitted on textile machines following thermal stabilization; monofilament tension and weave pattern are precisely controlled for pore accuracy before heat setting and post-treatment.

Final product types

• High-precision woven filter meshes
• Mesh belts for food dewatering lines
• Filter cartridges for water and chemical processing
• Screen printing fabrics for electronics and packaging

3. Medical Catheter Reinforcement

Medical device manufacturers employ this grade of nylon 12 monofilament in the reinforcement layers of high-pressure and micro-lumen catheter tubing. Its biocompatibility profile, proven dimensional control, and sterilization stability make it preferred for applications where consistent wall thickness and kink resistance are required during manufacturing and use.

Industry compliance standards

• ISO 10993 (Biological Evaluation of Medical Devices)
• USP Class VI Testing
• EU MDR 2017/745
• 21 CFR 820 (Quality System Regulation for Medical Devices)

Typical usage ratio

• Monofilament reinforcement typically forms 5–15% of the total catheter wall volume, with ratios optimized for target burst pressure and desired lumen flexibility in coronary, peripheral, or neurovascular devices.

Downstream process integration

• Embedded within multi-layer catheter wall structures via continuous extrusion; filament winding, braiding, or spiral wrapping occurs before final extrusion or co-extrusion of polymer jackets and lumen.

Final product types

• Angiographic catheters
• Balloon dilation catheters
• Cannulae for minimally invasive surgery

4. Sports Racket Strings and Fishing Lines

This monofilament is the primary material in high-durability racket strings and competition-grade fishing lines, where exceptional abrasion resistance and controlled stiffness are necessary. Sports equipment manufacturers leverage its stress-strain characteristics and low water absorption during string and line fabrication for consistent performance across diverse environmental conditions.

Industry compliance standards

• Racket Sports Industry Association (RSIA) string performance protocols
• ISO 1806 (Fishing nets — Determination of mesh-breaking force)
• Applicable national sports equipment safety standards
• RoHS Directive 2011/65/EU (for consumer export products)

Typical usage ratio

• Used as the sole monofilament (100%) in high-performance lines and racket strings; gauge and strand assembly are customized, ranging from 0.50 mm to 1.40 mm in diameter to balance strength and elasticity for specific playing or fishing applications.

Downstream process integration

• Extruded, surface finished (plasma or polymer coating), and precision wound; for racket strings, additional thermal stretching is applied to achieve target modulus, while fishing lines may undergo ultraviolet stabilization and multi-strand braiding.

Final product types

• Tennis and badminton racket strings
• Premium angling mono and braided lines
• High-strength stringing for squash and racquetball

5. Cable Sheathing and Electrical Harnessing

Electrical harness quality and industrial cable sheaths benefit from the longevity, flexibility, and chemical resistance of this nylon 12 monofilament. Wire harness producers select it to braid or wrap around control cables and sensor wires, especially in automotive, aviation, and process automation where abrasion and chemical exposure are routine operating conditions.

Industry compliance standards

• UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords)
• ISO 6722 (Road Vehicles – Low-Voltage Cables)
• EN 50525-2-11 (Electric cables - Polyvinyl chloride sheathed cables - General requirements and tests)
• REACH Regulation (EC) No 1907/2006

Typical usage ratio

• Forms between 5–20% of total cable sheath or harness structure by weight; the proportion is set based on the cable’s diameter, required flame resistance, and flexibility criteria for moving or static installations.

Downstream process integration

• Monofilaments are incorporated as braided sleeving or spiral wraps during the final cable assembly or at the over-braiding post-extrusion stage; additional thermal or UV stabilization is carried out for demanding outdoor or automotive settings.

Final product types

• Braided cable sleeving for automotive and industrial panels
• Electrical wire harnesses for transportation and machinery
• Protective cable binders for automation systems
