PA66 Engineered Plastics for Superior Performance

Welcome to ttindustrygroup, your source for high-quality PA66 polymer solutions. We offer a vast range of PA66 plastic products for manufacturers across the automotive, consumer goods, and industrial equipment industries.

This comprehensive guide will educate you on the advantages and applications of PA66 and working with this exceptional engineering thermoplastic.

Introduction to PA66 Plastic

PA66, also known as nylon 66, is a thermoplastic polymer created from hexamethylenediamine and adipic acid. With its unique molecular structure, PA66 offers enhanced mechanical properties, heat resistance, and chemical stability compared to other synthetics.

Our PA66 lineup includes various glass fiber reinforced grades from PA66 GF15 to PA66 GF60 (PA66 GF15, PA66 GF20, PA6 6 GF25, PA66 GF30, PA66 GF33, PA66 GF35, PA66 GF50, PA66 GF60, and PA66 FR, PA66 GF FR) for modulus and strength tailoring. We also provide specialty products like flame retardant PA66 for safety compliance.

Custom formulations are available to achieve specific requirements like UV resistance, electrostatic dissipation, wear resistance, smooth surfaces, and more.

PA66 Uses in Automotive Manufacturing

The automotive sector leverages PA66 for under-hood components, electrification, and lightweight demands.

Heat deflection temperatures exceeding 200°C make PA66 suitable for air intake manifolds, coolant pipes, cylinder head covers, fuel line connectors, and other engine and transmission parts.

Flame retardant grades like PA66 GF FR withstand automotive flammability standards, allowing usage in battery trays, electrical harnesses, and circuit boards.

Lightweighting needs for better fuel efficiency and vehicle electrification rely on PA66 for metal replacements. PA66 can substitute steel or aluminum in gears, pulleys, clutch pedals, and more.

Usage in Sports Equipment and Consumer Goods

PA66 strikes an ideal balance of flexibility, strength, and resistance for sports gear and daily merchandise.

The polymer withstands repetitive motions and wear, suiting it for ski bindings, bicycle sprockets, inline skate frames, telescope lenses, and camera mounts.

Blends like PA66 GF15 enhance stiffness for golf club shafts yet maintaining enough resilience. We can customize grades tackling golf ball backspin without sacrificing club durability.

Flame retardant, self-lubricating, and impact-modified PA66 grades make perfect choices for consumer electronics like power tool housings, laptop frames, and device covers.

Food contact-approved grades facilitate use in cutlery handles, blender jars, coffee makers, and other kitchenware items. Easy moldability allows intricate cookware design geometries.

Versatility in Industrial Components

PA66 offers engineers cost-effective design freedom for the most demanding mechanical parts across B2B sectors:

Precisely machined PA66 gears and rollers withstand heavy loads, vibration, and wear while running quieter than metal alternatives. Glass bead filler assists friction resistance in conveyors and sorters’ equipment, contacting thousands of parcels daily.

Medical and laboratory gear integrates insulated, autoclavable PA66 for filter housings, test tube racks, sterile hospital pallets, and biopsy forceps. Neutral colorants ensure sample purity for scientific procedures.

High CTI property suits PA66 for electrical insulators, switch boxes, transformer bobbins, and connector bases facing temperature fluctuations, pollution, and arc events.

We extrude PA66 in all custom cross-sections for slide bearings. Lubricant-impregnated grades achieve superior dynamic load handling, surface finish, and noise reduction in rotating shafts.

Leveraging PA66 Performance

Optimizing PA66 strength-to-weight ratio and longevity requires proper design and machining techniques:

Mold simulations predict shrinkage rates. We suggest melt temperatures around 275~295°C and mold surfaces above 150°C for intricate detailing with max heat resistance. PA66 can fuse in automated assembly.

Glass filler above 30% significantly hampers materials flowability. Minimize draft angles and radii restrictions for greater cost savings. Ejector pin density should match fill ratio.

Low friction cutting on automated lathes, drills, and milling centers maximizes part quality. Carbide tooling resists abrasion at 10,000+ RPM and cutting speeds reaching 500 m/min. Intermittent lubricant flooding prevents chip welding.

If adhesive bonding falls short, join PA66 parts via heat staking, vibration welding, or thread fasteners. Always test prototype interfaces first.

1. What are the main benefits of PA66 over other thermoplastics?
Some key advantages of PA66 are higher strength, enhanced heat resistance, excellent chemical stability, and good electrical insulation properties compared to plastics like nylon 6, polyethylene, and PET. This allows PA66 to withstand demanding environments.

2. What types of reinforcements can you add to PA66?
Common reinforcements include glass fibers (15% to 60%, PA66 GF15, PA66 GF20, PA6 6 GF25, PA66 GF30, PA66 GF33, PA66 GF35, PA66 GF50, PA66 GF60,and PA66 FR, PA66 GF FR), minerals, heat stabilizers, wear resistance additives, flame retardants, impact modifiers, internal lubricants, and more. These enhance physical properties and functionality.

3. Is PA66 modified for food contact compliance safe for equipment?
Yes, our food contact grades have FDA/EU 10-2011 certification for equipment safety. Special formulations ensure compliance for food processing, cooking, and storage applications while optimizing durability.

4. How should you machine and finish PA66 parts?
PA66 parts can be machined by lathing, milling, drilling, and tapping with optimized tool geometries, and flood coolants. Finishing processes like media blasting, vibratory grinding, or chemical polishing achieve smooth surfaces resisting wear and contamination.

5. Can you weld or bond PA66 with other plastics and materials?
Joining PA66 requires testing for each combination considering thermal dynamics and chemical compatibility. Methods include ultrasonic, friction, vibration, hot plate, laser welding with other synthetics, and thermoplastics. Adhesive bonding depends on surface treatment and primers.
