Polyolefin
Polyolefins fall into the family of thermoplastics with one unique characteristic: an oily or waxy feel to the material when sanded or ground. Polyolefin lends itself very well to remolding through the use of heat. Because of this, components made of this material lend themselves well to the possibility of plastic welding. Most adhesive repair materials and paint will not bond to the surface of a polyolefin unless an adhesion promoter specially formulated for plastic is first applied to the exposed raw surface. Otherwise, polyolefins are repaired like most other thermoplastics. Polyolefins are used in bumper covers, fan shrouds and wheel housings.
Proper identification of the various types of plastic is necessary to select the appropriate repair method(s) to carry out high quality plastic repairs. For additional information, refer to: Plastic Repairs (501-25 Body Repairs - General Information, General Procedures). .
