What Are You Looking For?
In the realm of logistics and transportation,especially for small refrigerated vehicles and vans,maintaining the integrity of the internal temperature is crucial for preserving the quality of perishable goods.This is where sealing strips made from materials like PVC(Polyvinyl Chloride)and EPDM(Ethylene Propylene Diene Monomer)play a vital role.
Material Characteristics
PVC Sealing Strips
• Durability and Flexibility:PVC is known for its robustness and flexibility,which makes it ideal for environments where the sealing strip might face frequent physical stress.It can withstand the rigors of daily use without losing its shape or integrity.
• Insulation:PVC has good insulating properties,which help in maintaining the internal temperature of the refrigerated vehicle.This is particularly important in preventing heat exchange between the inside and outside of the vehicle.
• Water Resistance:PVC is inherently water-resistant,which means it can effectively prevent water ingress,a common issue in humid or rainy conditions.
EPDM Sealing Strips
• Temperature Resistance:EPDM can withstand extreme temperatures,making it suitable for both hot and cold climates.It remains flexible and functional even at very low temperatures,ensuring that the seal remains intact.
• Chemical Resistance:EPDM is resistant to a wide range of chemicals,including acids,alkalis,and salts.This makes it highly durable and long-lasting,even in harsh environments.
• Non-Absorbent:EPDM does not absorb water,which is crucial for maintaining the seal and preventing moisture from entering the refrigerated space.
Application in Small Refrigerated Vehicles and Vans
In small refrigerated vehicles and vans,the sealing strips are typically installed along the door seams.Their primary functions include:
• Insulation:By creating a tight seal,the strips prevent cold air from escaping and warm air from entering the vehicle.This helps in maintaining a consistent internal temperature,which is essential for preserving perishable goods such as food,pharmaceuticals,and other temperature-sensitive items.
• Waterproofing:The strips act as a barrier against water,preventing leaks and moisture from entering the vehicle.This is particularly important during rainy weather,as any water ingress can compromise the integrity of the refrigerated space and potentially damage the goods being transported.
Installation and Maintenance
Proper installation of the sealing strips is crucial for their effectiveness.They should be fitted snugly along the door seams,ensuring a tight seal when the door is closed.Regular maintenance,such as checking for wear and tear and replacing the strips when necessary,is also important to ensure continuous performance.
Sealing strips made from PVC and EPDM are indispensable components in small refrigerated vehicles and vans.They provide effective insulation and waterproofing,ensuring that the internal environment remains stable and protected.By choosing high-quality sealing strips and ensuring proper installation and maintenance,logistics operators can significantly enhance the efficiency and reliability of their refrigerated transportation systems.
