The Application of Masterbatch Foaming Agent

Our masterbatch-type foaming agent you described (moderate decomposition rate, fine cell structure, suitable for extruded sheets/boards/profiles of PP, PE, PVC, ABS), this foaming agent is highly suitable for manufacturing plastic products that require lightweighting, thermal/acoustic insulation, cushioning, cost reduction, and a relatively smooth surface or uniform structure.

Here are specific application areas and product examples:

1. Extruded Boards:

• Building Insulation/Acoustic Panels: Thermal insulation layers for walls, roofs, subfloors (e.g., alternatives or supplements to XPS, especially PP or PE based). Acoustic barrier panels.

• Signage & Decorative Panels: PVC foamed boards (e.g., Sintra board, Andy board) widely used for advertising display boards, signs, window displays, indoor/outdoor decoration, model making. Fine cell structure ensures better surface printability and workability (e.g., engraving, cutting).

• Padding/Backing Boards: Cushioning inserts in industrial packaging, lining boards for luggage/cases, exhibition flooring boards, drawer liners.

• Furniture Boards: Used as cabinet backs, drawer bottoms, or lightweight furniture components (sometimes laminated with wood-grain finishes).

• Automotive Interior Panels: Door panel liners, trunk liners (requiring lightweighting and sound insulation).

  
  

2. Extruded Sheets:

• Packaging Sheets: Thermoformed into various food packaging trays (e.g., fresh produce trays, cake trays), electronics cushioning inserts, industrial part packaging liners. Foamed sheets are lightweight, offer good cushioning, and are cost-effective.

• Disposable Items: Cups, lids, food containers (especially thermoformed PP foamed sheets).

• Floor Mats/Flooring: Picnic mats, yoga mats (commonly PE foamed sheets), children's play mats, changing room mats.

• Stationery/Desk Mats: Writing pads, base materials for mouse pads.

  
  

3. Extruded Profiles:

• Sealing Strips: Door/window sealing strips (PVC foamed seals are very common), requiring softness, good elasticity, sealing performance, and lightweighting.

• Decorative Moldings: Baseboards (skirting boards), crown moldings, picture frame moldings, furniture edge banding (PVC or ABS foamed profiles). Foaming reduces weight, lowers costs, and improves workability (e.g., nailing, cutting).

• Furniture/Architectural Profiles: Such as shutter slats, curtain rods, frames or connectors for simple furniture.

• Protection Strips/Edge Trims: Impact protection strips for table edges, corners, and equipment.

• Cable Sheathing/Conduits: Protective sheathing or conduits requiring flexibility and insulation (PE or PVC foamed).

Core Advantages Delivered:

• Lightweighting: Foaming reduces density, saving material costs and reducing product weight.

• Thermal/Acoustic Insulation: A fine, closed-cell structure effectively blocks heat and sound transmission.

• Cushioning/Shock Absorption: The cellular structure absorbs impact energy, protecting contents or providing comfortable feel (e.g., mats).

• Cost Reduction: Achieved through reduced density (using less resin).

• Improved Processability/Appearance: The "fine cell structure" is key, ensuring:

• Smoother product surfaces, reducing defects like "sharkskin," and enhancing appearance.

• More uniform structure, leading to more stable mechanical properties (e.g., flexural strength).

• Easier post-processing (e.g., printing, laminating, cutting, thermoforming).

• Compatibility with Extrusion Process: The "moderate decomposition rate" is particularly suitable for extrusion, allowing stable gas release within the extruder barrel and die to form uniform cells. This avoids problems caused by decomposition that is too fast (gas escape, cell collapse) or too slow (insufficient foaming).

In summary, this foaming agent is an ideal choice for producing various lightweight, functional plastic boards, sheets, and profiles. It is broadly applicable in construction/building materials, advertising/decoration, packaging/transportation, household goods, and automotive components.

The specific resin choice (PP, PE, PVC, ABS) depends on the required physical properties of the final product (e.g., temperature resistance, flexibility, strength, flame retardancy), cost considerations, and processing requirements.
