Kingsville, Ontario Canada; Vinyl is not a natural substance but is a synthetic man-made material. It is a type of plastic that is made from ethylene (found in crude oil) and chlorine (found in regular salt). When processed, both the substances are combined to form Polyvinyl Chloride (PVC) resin, or as is commonly referred to – Vinyl.
Some common properties of vinyl are that vinyl is resistant to moisture and humidity. It is a very strong and durable plastic material.
Many of growers may have come across the terms vinyl siding, vinyl records, vinyl flooring, vinyl , but may not know about vinyl greenhouse plastic.
For several decades Italian made PATILUX plastic coverings has offered growers worldwide transparent thermal covers that contribute to higher yields and quality; when the crops is in need of protection with light conditions and thermal specifications.
According to Wikipedia, EVA is a polymer that approaches elastomeric (“rubber-like”) materials in softness and flexibility. This is distinct from a thermoplastic point of view. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl products in many electrical applications.
Vinyl greenhouse plastic Patilux offer growers exceptional transparency to sunlight visible, particularly in the PAR (Photosynthetic Active Radiation, Active Radiation for photosynthesis, ie 400-700 nm) necessary for the growth of all green plants.
Excellent thermal effect that limits the temperature drop during the night or in poor sunlight. High mechanical characteristics of flexibility, tensile strength, tear and perforation, even at very low temperatures.
Persistence in time of both the brightness of the mechanical characteristics. PATILUX is therefore ideal application for crops requiring as an essential factor the intensity of natural sunlight, even in critical seasonal periods of lower solar radiation, allowing early harvesting and high quality of both flowers and horticultural products.
