Pay attention to the characteristics of EVA road cones and produce high quality ones
The EVA road cone is a good and frequently used warning. It is no longer unfamiliar to me and us. It can be seen on the road, at city junctions and near dangerous buildings.Its existence reminds us of the importance of safety and brings security to our life.Road cones are used to be placed in the middle of roads, dangerous areas and road construction sites, etc., in places where it is necessary to temporarily separate traffic flows, guide traffic, direct vehicles to bypass hazardous sections, and protect construction site facilities and personnel or other appropriate locations.
EVA road cones are made by the copolymerization of ethylene (E) and vinyl acetate (VA).EVA has good flexibility and elasticity of rubber, under - 50 ℃ can still has good flexible, good transparency, or surface gloss, good chemical stability, anti-aging and good ozone resistance strength, non-toxic.Good blending with filler, coloring and shaping.
There are a number of reasons for the EVA road cones themselves.The characteristics of EVA road cones are mainly related to the control of raw materials. EVA is a copolymer of ethylene-vinyl acetate (vinyl acetate).When the content of vinyl acetate is increased, its elasticity, softness, solubility and transparency are also improved.When VAC content decreases, the performance is close to polyethylene, with increased rigidity, wear resistance and electrical insulation.When the content of VAC is certain and the melt index increases, the softening point decreases. The processing and surface gloss improve but the strength decreases. Otherwise, with the decrease of MI, the molecular weight increases and the impact performance and the resistance to environmental stress cracking improve.This characteristic, when making EVA road cones, should be well controlled. If you want the characteristic deviation of road cones, the quality will be greatly affected.
