Polar PVC Strip Curtain: Adaptation to Low-Temperature Environments of Varying Degrees

Refrigeration and freezing facilities across the food industry cover a wide temperature spectrum, and each operating scenario imposes distinct requirements on low-temperature resistance for isolation materials. The table below outlines typical operating parameters for mainstream refrigeration and freezing equipment:

PVC strip curtains serve as critical thermal isolation components for cold storage doorways, minimizing cold air leakage, stabilizing indoor temperature and cutting refrigeration energy consumption. However, different cold storage environments carry divergent low-temperature challenges. Conventional PVC material tends to lose flexibility, turn brittle and crack under sub-zero conditions, so proper grade selection is essential according to actual working temperature.

Our standard Polar PVC Strip Curtain has a stable operating temperature range from -30℃ to +50℃. It maintains good flexibility, impact resistance and tear resistance under continuous sub-zero operation, avoiding hardening or fracture under frequent forklift and pedestrian passage. This grade fully satisfies most of the refrigeration and freezing scenarios listed above. Thanks to its balanced performance and cost efficiency, it remains the preferred option for the majority of cold chain customers.

Nevertheless, certain special refrigeration facilities demand superior low-temperature performance. Deep cold storage, for example, is deployed for high-value tuna, premium seafood and specific chemical raw materials, operating at far lower temperatures. Under such extreme working conditions, standard Polar PVC Strip Curtain may gradually lose pliability and fail to deliver reliable long-term isolation performance. For these extreme cold projects, upgraded ultra-low temperature resistant Polar strip curtains are required to match the harsher operating conditions.

To meet diversified cold chain demands from global clients, China CONET has developed a complete portfolio of low-temperature resistant PVC strip curtains. The product lineup includes the -40℃ low-temperature grade, as well as ultra-low temperature versions capable of stable operation down to -50℃. Customized material formulations ensure the strips retain elasticity and structural integrity under sustained ultra-low temperature exposure, effectively solving the thermal isolation challenge for deep cold warehouses and ultra-low temperature processing workshops. With consistent quality and full compliance with relevant food contact and REACH requirements, CONET Polar PVC strip curtains deliver reliable thermal barrier solutions for the whole cold storage industry.
