PP Non-woven Honeycomb Core – 6 Key Advantages for Resin Coating

3rd, June 2026

Designed for resin composite processes, solving coating pain points for downstream manufacturers. Six core advantages:

1. Uniform resin penetration in one pass
The double-sided non-woven fabric features natural capillary wicking. Resin automatically infiltrates and flows into honeycomb cell walls after coating – no repeated rolling needed. Coating time per panel reduced by 70%.

2. Finished product yield jumps to over 95%
Conventional cores achieve only ~75% yield due to uneven penetration and delamination. With our product, first-pass yield exceeds 95%, reducing scrap loss by 80%.

3. Peel strength doubles
Non-woven fibers form micro-mechanical interlocking with cured resin – peel strength is 2–3 times that of ordinary smooth cores, completely eliminating skin detachment.

4. Dimensional stability – no warping or deformation
PP substrate is heat-stabilized, remaining flat during resin curing exotherm (50–80°C). Post-molding trimming time reduced by 60%.

5. Lightweight and material saving
Core density as low as 60 kg/m³ – 15–20% lighter than conventional products. Uniform penetration also saves 15–20% resin, lowering total material + labor cost by 10–15%.

6. 100% recyclable – environmentally compliant
Both PP and non-woven fabric are recyclable, meeting EU, Japan and other market environmental regulations – helping downstream exporters pass compliance easily.
