PPS

The best adhesive for PPS is typically High-Strength Epoxy, with excellent bond strength. As a plastic material, PPS has unique bonding characteristics that require specific adhesive selection. PPS has low surface energy, which makes it challenging to bond without proper surface preparation or specialized adhesives. Common applications include automotive,chemical-processing.

Bonding PPS requires understanding its unique surface properties and chemical characteristics. As a plastic material, PPS presents specific challenges that can be overcome with the right adhesive selection and proper surface preparation techniques. This comprehensive guide provides expert recommendations, bond strength data, and step-by-step instructions to achieve strong, durable bonds with PPS.

Material Properties & Characteristics

PPS exhibits low surface energy, which requires specialized adhesives or surface treatments to achieve reliable bonding. The none nature of PPS presents bonding considerations that depend on surface preparation and adhesive selection. As a rigid material, PPS benefits from rigid adhesives that provide maximum structural strength and dimensional stability. The very-high chemical resistance of PPS requires adhesives compatible with its chemical composition and environmental exposure conditions. Understanding these fundamental properties is essential for selecting the appropriate adhesive and surface preparation method.

Surface Preparation Best Practices

Achieving strong, durable bonds with PPS depends heavily on proper surface preparation. Low surface energy materials like this require thorough cleaning with solvents such as isopropyl alcohol to remove oils, fingerprints, and contaminants that can interfere with adhesion. Surface activation techniques including flame treatment, corona discharge, or plasma treatment may be necessary to increase surface energy and improve wetting by adhesives. Ensure surfaces are at room temperature (15-25°C or 60-80°F) for optimal bonding conditions. Temperature extremes can affect adhesive flow, wetting, and cure times. Apply adhesive within minutes of surface preparation to prevent recontamination from dust, moisture, or oils. Proper surface preparation significantly improves bond strength, durability, and long-term performance.

Why PPS Requires Special Attention to Bond

Low Surface Energy

Materials with low surface energy resist wetting by adhesives, making mechanical bonding difficult. Surface treatments like corona discharge, plasma treatment, or primers are often necessary.

Surface Preparation Guide

Proper surface preparation is critical for achieving strong, durable bonds with PPS. Follow these steps:

  1. Clean surfaces with isopropyl alcohol to remove oils and contaminants
  2. Consider flame treatment or plasma surface activation to increase surface energy
  3. Use adhesion promoters or primers designed for low-energy surfaces
  4. Ensure surfaces are at room temperature (60-80°F) for optimal bonding
  5. Apply adhesive within minutes of surface preparation for best results
