Introduction The synthesis of polymeric materials, using renewable resources, has been subject of research in the last decades.
Polyurethanes are becoming increasingly important as engineering materials because they have excellent abrasion resistance and the properties of both elastomers and plastics.
Although, polyurethane are very versatile polymeric materials and widely used in foam, elastomers, plastics, adhesives, coating, leather-like materials and finishes but they show poor thermal resistance and barrier properties, which limit their applications.
Experimental 2.1 Materials The diisocyanate used was toluene diisocyanate (TDI) constituting the mixed 2,4: 2,6 isomers in 80120 ratio .
PI20043190, used materials i.e. : palm oil based oleic acid ; glycerol, systerm ; 4-dodecylbenzenesulfonic acid, fluka ; extruded 3A molecular sieve, Aldrich), Kunipia F (suPUlied by Kunimine Ind.

The results showed that the loose state was related to vibration frequency, fitting clearance, friction coefficient, element materials.
Not only the bolt material will affect the anti-loosening characteristic, and the fitting part materials, such as nut or gasket, will also affect the fasteners’ anti-loosening characteristic.
The reason is the surface roughness and mechanical properties of the materials are different.
