The production of high-quality cold room pvc strip curtains involves a meticulous multi-stage extrusion process designed to ensure durability, clarity, and optimal performance under challenging conditions. The journey begins with the careful compounding of virgin PVC resin, which serves as the foundational polymer. To achieve the required flexibility and low-temperature performance crucial for cold storage environments, specialized low-temperature plasticizers, such as DOTP (Dioctyl Terephthalate) or DINP (Diisononyl Phthalate) for superior flexibility and environmental compliance, are precisely blended with the resin. This blend also incorporates UV stabilizers to prevent degradation from ultraviolet light exposure, anti-fungal agents, and other additives that enhance specific properties like clarity and fire retardancy. The compounded material is then fed into an industrial extruder, where it is heated to a molten state and forced through a precisely designed die. This die shapes the molten PVC into continuous strips of uniform thickness and width, which is a critical step for consistent performance.
Following extrusion, the hot PVC strips undergo a rapid cooling and calibration process, typically involving a series of water baths or cooling rollers. This phase is crucial for solidifying the material quickly while maintaining its precise dimensional stability and surface finish, preventing warping or unevenness. Once cooled, the continuous strips are then cut into predetermined lengths, which can vary based on the specific door opening requirements. The final stages involve quality control assessments, where each batch is rigorously tested against established benchmarks. This includes checks for thickness uniformity using precision calipers, visual inspection for clarity and absence of defects, and critical performance tests such as Shore A hardness (typically between 75-85 for optimal balance of flexibility and durability), tensile strength, and low-temperature flexibility, often verified at temperatures down to -40°C or -50°C. Compliance with international standards such as ISO 9001 for quality management, RoHS (Restriction of Hazardous Substances), and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) ensures the product meets stringent safety and environmental regulations. For food contact applications, specific formulations may also adhere to FDA standards, guaranteeing the material’s inertness and non-leaching properties. The typical service life of properly maintained heavy duty plastic curtains in demanding environments can exceed five to seven years, depending on traffic volume and environmental exposure.
The advantages of this precise manufacturing process are manifold.
