PVC sealing strips are made of polyvinyl chloride (PVC) as the main raw material, with plasticizers and other ingredients added. They have heat resistance, toughness and ductility, and are mainly used in the door and window, furniture, automobile and curtain wall manufacturing industries. Its production process includes raw material preparation, mixing, extrusion molding and other links. The microwave vulcanization process can improve the surface finish and elasticity. The applicable temperature range is -40℃ to +120℃.
High-quality products are identified by their characteristics such as not softening at high temperatures and not breaking easily at low temperatures. When burned, they emit black smoke and leave hard residues. The density is 1.4-1.6; inferior products often have poor elasticity and are prone to aging and shrinkage due to excessive talcum powder filling. Silicone rubber sealing strips have a wider temperature resistance range (-50℃ to 200℃), burn smokelessly and odorlessly, and have a lower density (1.1-1.25) [1]. This product supports customized services and can meet the needs of scenarios such as insect control and sound insulation

Customization process:
1. Contact us: Clarify the purpose of PVC sealing strips, if you have specific requirements specifications,please send an email or WhatsApp to contact us(+86 188 2072 7151)
2. Prepare Raw Materials: According to the purpose and performance requirements of the extruded profiles, PVC or PE ABS PP PMMA raw materials with different polymerization degrees and models can be selected.
3. Extruder preheating: The heating device heats each section of the extruder barrel to the set temperature. Generally, the material is divided into the feeding section, compression section and metering section, and the temperature of each section is different.
4. Extrusion molding:Add the mixed dry blend into the preheated extruder barrel. As the screw rotates, the material is transported forward in the barrel. Finally, under the action of the die, the designed shape is extruded.
5. Cooling & Shaping: The PVC sealing strips extruded from the extruder head has a high temperature and needs to be cooled and shaped immediately to maintain its shape. Usually a vacuum sizing water tank is used for cooling and shaping.
6. Sample testing: If the sample test is qualified, a batch order will be placed. If it is unqualified, the sample will be remade.
7. Mass production: Sign a bulk purchase and sale contract.After confirming the samples, the production stage will be entered. The printing quality (such as ink dots and registration deviation) and die-cutting accuracy will be monitored.
Conventional products are 0.6-1.6MPa, and customized products can reach up to 2.5MPa (such as fire-fighting pipes).
A: Standard products comply with BS EN 61386 flame retardant B1 level, and can be customized to V-0 level (UL94).
A: -40℃~120℃ (short-term resistance to 150℃), suitable for automotive engine compartment parts.
±0.1mm (precision grade) or ±0.3mm (general grade), which is better than the national standard GB/T 8814.
Supports 3-layer co-extrusion, color difference ΔE≤0.5, surface hardness ≥2H (such as high-end decorative lines).
Only purchase from TOP5 manufacturers such as Dow Chemical and LG Chemical, and each batch is accompanied by the original factory warranty.
18 inspection nodes: raw material entry inspection → online diameter gauge monitoring → 72-hour weathering test, etc.
Free replenishment during the warranty period (defect evidence must be provided), and a rectification report will be issued within 48 hours.
It is recommended to use a cold-resistant formula (-40℃ impact strength ≥50kJ/㎡), which has been applied to Canadian municipal projects.
Medical-grade PVC is certified by ISO 14644-1, and the TVOC release is ≤0.01mg/m³.
