The sheeting also keeps the concrete from clogging the gravel layer when the slab is poured.
													
																	Fuel resistant plastic sheet. 
									
	
		
	
																	Fel pro 3060 gasket material. 
																	Polyethylene or a vapor retarder on top of the gravel to prevent the soil gases from entering the house. 
																	My need was to make replacement gaskets for my plastic gas jugs. 
																	I bought this 1 8 material and tried again. 
															
													
									
	
		
	
																	We developed 3m scotch weld fuel resistant coating ec 776 as a general purpose solvent based adhesive coating that provides good adhesion to synthetic rubber metal glass and many plastics. 
																	Place heavy duty plastic sheeting 6 mil. 
																	Acetal plastic sheet rod tube and accessories acetal polyoxymethylene or pom provided by interstate plastics is a tough machinable thermoplastic with a high modulus of elasticity high strength good rigidity dimensional stability and resistance to moisture chemicals and solvents. 
																	You can soften it a long way relatively easily then force it into a shape you want by pressing bu. 
															
													
									
	
		
	
																	Plastic sheeting or vapor retarder. 
																	It has desirable toughness properties performing well at extreme temperatures and under fatigue endurance. 
																	You won t have much luck melting it though it slumps but never flows. 
																	A no attack possibly slight absorption. 
															
													
									
	
		
	
																	Some swelling and a small reduction in mechanical likely. 
																	Unless i m mistaken common polyethylene is entirely tolerant of gasoline. 
																	Permatex 85420 permashield fuel resistant gasket dressing sealant 2 oz tube 4 5 out of 5 stars 197. 
																	Negligible effect on mechanical properties. 
															
													
									
	
		
	
																	Have a question on the chemical resistance of plastics. 
																	Ask a plastic expert. 
																	In my case 1 16 was just a bit too thin for a good seal.
