Electrical insulation It is used to make up for the shortcomings of polyvinyl acetate hardening when cold, and the population is too soft after saliva, and the amount of polyvinyl acetate accounts. Another reason come from the randomness in its repeating unit composition. Due to its high molecular weight, polybutene does not tend to crack when subject to stress and therefore gives the elastic raw material a high level of flexibility. Other features include low noise transmission, low linear thermal expansion, no corrosion and calcification.
