Product Deep Dive: Ribbed Yellow PVC Strip Curtain - Technical Features & Specifications

1. Advanced Material Composition & Formulation

The core of our product is a proprietary Unplasticized Polyvinyl Chloride (UPVC) compound, engineered for superior performance in industrial environments.

• High-Molecular-Weight PVC Resin: We use virgin, high-purity PVC resin as the base polymer. This ensures consistent molecular chain length, which directly translates to:
  • Higher Tensile Strength: Resists stretching and deformation under its own weight or from impact.
  • Improved Durability: Withstands millions of flexing cycles without fatigue failure at the hanging point.
  • Greater Tear Resistance: Prevents nicks and cuts from propagating across the strip.
• Precision Plasticizer System: Unlike standard PVC, our UPVC uses a minimal, non-migrating plasticizer package. This means:
  • No Leaching or Stickiness: The strips will not exude plasticizers over time, preventing a sticky surface that attracts dust and dirt—a critical feature for the high humidity of Kota Kinabalu or Kuching.
  • Long-Term Flexibility: The flexibility is engineered into the polymer matrix, not dependent on additives that can evaporate, ensuring the strip remains supple for years, even in the cold conditions of a Brunei cold storage facility.
• Stabilizer & Modifier Package:
  • Thermal Stabilizers: Protect the polymer from degradation during extrusion and in high-temperature environments (e.g., near ovens in Sandakan food plants).
  • Impact Modifiers: Microscopic additives that absorb and dissipate energy from impacts (e.g., forklift collisions in Bintulu warehouses), preventing cracks and breaks.
  • UV Stabilizers: Shield the polymer chain from ultraviolet radiation, preventing yellowing and embrittlement, which is crucial for strips near loading bay doors.

 

2. Precision Ribbed Texture: Form & Function

The ribbed design is a critical functional feature, not just an aesthetic choice.

• Ridge Geometry: Each ridge is precisely formed with a 0.5mm height and a 0.8mm pitch (distance between ridges). This specific geometry is optimized for:
  • Structural Rigidity: The ribs act like structural I-beams, increasing the strip's resistance to bending and twisting in high-traffic areas, ensuring it swings true and returns to a sealed position.
  • Enhanced Grip: The ridges provide a high-friction surface, allowing personnel in Miri's workshops to easily push through heavy strips without slipping.
  • Optical Clarity: The ribs reduce surface contact when strips are overlapped, minimizing light diffraction and "frosted glass" effect. This provides a remarkably clear view for forklift operators in Labuan ports, enhancing safety.

 

3. Optical Engineering & Insect Repellency

The yellow colour is a feat of optical engineering for pest management.

• Wavelength-Specific Pigmentation: We use organic and inorganic pigments calibrated to emit and reflect light predominantly in the 575-590 nanometer range (yellow spectrum). This specific wavelength:
  • Confuses Phototactic Insects: Flying insects like houseflies and mosquitoes use photoreceptors to navigate. This yellow band overwhelms their senses, creating a visual disturbance that repels them without chemicals—essential for MeSTI-certified facilities in Papar.
  • Maintains Human Visibility: The chosen hue allows for high luminous transmittance (~85%), ensuring the area behind the curtain is well-lit and visible to the human eye, maintaining a safe working environment.
• Clarity & Transparency: The formulation ensures exceptional optical clarity without blurring or distortion, a key safety feature for doorways in Bandar Seri Begawan's busy factories.

 

4. Detailed Physical & Mechanical Properties

 

Property	Test Method	Value	Significance for Borneo Clients
Thickness	ISO 4593	2.0 mm ± 0.1 mm	Heavy-duty; can withstand impact from pallet jacks common in Kuching warehouses.
Width	ISO 4592	200 mm ± 2 mm	Ensures consistent 25-30% overlap when installed, creating an effective seal.
Specific Gravity	ISO 1183	1.30 - 1.35	Indicates high-quality, dense material without filler additives.
Tensile Strength	ISO 527	> 20 MPa	Resists stretching and tearing, crucial for high-use doors in Sibu logistics hubs.
Elongation at Break	ISO 527	> 250%	Extremely flexible; will not snap or crack under impact or in Brunei's cold stores.
Low Temperature Flex	ISO 812	-25°C	Remains flexible in cold room environments, preventing shattering.
Fire Performance	UL 94	V-2 Rating	Self-extinguishing; enhances safety compliance in Samalaju Industrial Park.
Hardness (Shore A)	ISO 868	82 ± 3	The perfect balance: rigid enough to swing effectively, soft enough to absorb impact.

5. Performance Features & Operational Benefits

• Thermal Insulation (R-Value): The 2mm thickness and material density provide a measurable insulating effect, reducing heat transfer and significantly lowering energy costs for climate-controlled facilities across Sabah and Sarawak.
• Acoustic Dampening: The dense PVC material absorbs sound wave energy, reducing noise transmission by 12-15 decibels (dB(A)), creating a quieter work environment in loud manufacturing plants.
• Chemical Resistance: Resists weak acids, alkalis, oils, and fats. Can be easily cleaned with common industrial detergents, ideal for the demanding hygiene standards of Tawau's food processing industry.
• Hygienic Surface: The non-porous surface prevents the absorption of moisture and growth of mould, mildew, and bacteria, which is vital for the humid climate of Borneo.

 

6. Compliance & Certifications

• Food Contact Compliance: Formulated with ingredients that comply with international food contact regulations.
• Fire Safety: Achieves a UL94-V2 rating, meaning it will stop burning within 30 seconds after being removed from a flame.
• RoHS Compliant: Free from hazardous substances like lead, cadmium, and mercury.
