Description :

（SR‑S‑15P/20P/24P/32P、SS‑24P、MS‑40P，P=Integrated composite PET base film, non removable PET, all black microporous PU）

naming convention

• SR-S series: Universal low back pressure, ordinary non flame retardant PET foam (mainstream for mobile phone LCD)
• MS series: Low volatility+UL flame retardant PET foam (preferred for car/industrial control/battery)
• SS: SR improved ultra-thin soft version
• Suffix P: Foam+PET film hot pressing integrated, improving flatness, anti stretching, and convenient precision die-cutting

1、 SR-S series (conventional non flame retardant, low compression permanent deformation, main force in consumer electronics)

1. SR-S-15P | Density 150kg/m ³ | Softest model in the entire series

• thickness：0.5/0.7/1.0/1.5/2.0mm
• 25% compression force: 0.006MPa; Compression permanent deformation 1.0% (the smallest in the entire series, less prone to edge collapse)
• Features: Ultra soft, low pressure sensitive, excellent buffering, PET substrate does not elongate
• UseMobile phone screen buffer, camera dustproof, TWS headphone speaker dustproof, flexible screen frame gasket

2SR-S-20P | Density 200kg/m ³ | Ultra thin soft material

• Thickness: 0.3/0.4/0.5/1.0mm (preferred for ultra-thin)
• Compression load 0.006MPa, compression deformation 1.6%
• Features: Extremely thin, soft, ultra-thin module sealing
• Usage: Folding screen OCA shading pad, watch screen sealing, micro sensor buffering

3SR-S-24P | Density 240kg/m ³ | Top selling universal materialPORON

• Thickness: 0.7~3.0mm
• 25% CLD：0.008MPa， Compression residual 2.7%
• Features: Balanced softness and hardness, balanced sealing and dust prevention, with the highest cost-effectiveness
• Usage: Laptop LCD sealing, TV backlight pad, waterproof and dustproof tablet frame, Bluetooth headphone case sealing

4SR-S-32P | Density 320kg/m ³ | Slightly medium hard, with stronger sealing performance

• Thickness: 0.2~2.0mm (can be used as 0.2mm ultra-thin film)
• Compression force 0.011MPa, compression deformation 2.2%
• Features: Better support than the previous three models, higher resistance to compression, dust and water
• Usage: Sealing of car central control screen, dust prevention of power module, LED backlight shading foam, sealing of smart wearable housing

two、 SS-24P (SR-S-24P Improved Ultra Thin Special Edition)

• Density ≈ 240kg/m ³, with the same density as SR-24, the foam is more delicate and ultra soft
• Conventional thickness: 0.3/0.5/0.7mm, specializing in ultra-thin precision die-cutting
• Difference between SR-S-24P: Foam with smaller pore size, no coarse pores, and lower compressive stress
• Usage: Micro camera gasket, ultra-thin seal for watches, buffer for small IC chips

IIIMS‑40P（Flame retardant+low emission series, MS=flame retardant and low volatility, specifically designed for automotive/industrial control applications）

• Density 400kg/m ³ | Medium to high hardness, UL94-HB flame retardant, low VOC and low precipitation
• Thickness: 0.4~1.0mm, PET integrated backing
• 25% compression load 0.054MPa, compression deformation 3.0%; Temperature resistance better than SR series (long-term 85 ℃)
• Two major branches: MS-40P (PET non tearable), MS-40PR (PET peelable)
• Usage: Automotive instrument panel/car machine sealing, power battery module filling, industrial control power supply dust prevention, printer toner cartridge sealing, high temperature environment electronic products.
