BIRD NETTING διχτυ απωθησης ΝΕΤ 19mm (σπουργιτια) διασταση 20X20= 400 τ.μ.

Material Datasheet – 19mm Knotted Bird Netting Material: 12/6 twisted Polyethylene Mesh Size: 19mm Weight: 71 g/sqm Breaking Strain: 20 Kg per mesh Life Expectancy: 10 Years in normal usage Elongation Commercial polyethylene multifilaments have an elongation factor and break in the region of 20-30% Effects of Moisture Polyethylene is a paraffinic hydrocarbon and does not absorb water. Moisture does not affect the tensile strength of the net or any of the other mechanical properties. Effect of Low Temperature Polyethylene retains its flexibility at low temperatures. Softening Point The softening point of polyethylene fibres is in the region of 130-138°C and the fibre will melt at 150 – 160°C. The softening and melting points are determined by the nature of polymer and the way the crystallinity has been influenced during the treatment of the fibre after spinning. Effect of Sunlight Polyethylene is attacked by atmospheric oxygen, and the reaction is stimulated by sunlight. Polyethylene fibre will deteriorate on exposure to light; this effect is reduced by the inclusion of a UV inhibitor within the product. Chemical Resistance Acids – Excellent Alkalis – Excellent Polyethylene is inert to a wide range of chemicals. It’s high crystallinity tends to make it more resistant to chemicals that degrade olefin fibres.
