500ML Foam Expanding Liquid Expanding Insulation Mount Good Hardness Gap Filling Spray Pu Polyurethane Foam

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Gap Filling & Sealing: Expands to fill and seal gaps in door/window frames, electrical outlets, water pipes, and other structural joints.
  • Insulation & Mounting: Provides thermal and acoustic insulation while securely mounting objects with its hardened polyurethane foam.
  • Multi-Purpose Application: Designed for transportation, woodworking, packing, construction, and general insulation needs.

Key features

  • 1. Material Technology: Durable Polyurethane & Silicone Composition

    • With polyurethane and silicone-based formulation, achieve robust insulation and adhesion in harsh environments, outperforming traditional foams in longevity and temperature resistance*.

  • 2. Interactive Design: Precision Spray Nozzle & Applicator Tube

    • With the ergonomic spray nozzle and flexible applicator tube, easily target tight gaps and uneven surfaces for precise, mess-free application, simplifying DIY projects compared to bulk foam dispensers*.

  • 3. Performance Parameters: Rapid Expansion & High Hardness

    • With rapid expansion (reaching full size in seconds) and rigid cured foam (hardness exceeding 80 Shore A), quickly fill gaps and provide structural support, surpassing softer foams in durability for heavy-duty use*.

  • 4. Scenario Solutions: Multi-Purpose Versatility for Diverse Applications

    • Designed for construction, insulation, and transportation industries, effectively seal door/window frames, insulate electrical outlets, and secure cargo in both indoor and outdoor settings, offering broader utility than single-purpose sealants*.

  • 5. Certification Standards: Safety-Compliant Materials

    • With materials meeting safety and environmental standards (pending confirmation), ensure safe use around electrical systems and living spaces, aligning with industry best practices for insulation products*.

Supplier's note

  1. Technical Breakthroughs:

    • 35x Expansion (Pro Model): Outperforms industry benchmarks by 40%, enabling fills for larger gaps.
    • 3-Minute Curing (Pro): 70% faster than standard foams, ideal for on-site repairs.
    • -30°C–80°C Tolerance (Pro): Operates in extreme temperatures, expanding use cases to cold storage and industrial settings.

  2. Optimal Version Selection:

    • Base Model: Suitable for DIYers and small-scale projects requiring basic insulation (e.g., home repairs).
    • Advanced Model: Ideal for contractors needing faster curing (5 minutes) and moderate durability in moderate climates.
    • Pro Model: Best for industrial or extreme environments (e.g., automotive assembly, Arctic construction), where high expansion and temperature resistance are critical.

Pro Model’s 35x expansion ensures minimal material waste, reducing costs by 15% for large-scale insulation projects.
