From the initial Bakelite to polymers, plastics have developed into so many various types.
It has found use in nearly every industry – automotive, medical, kitchen, storage, furniture, electronics, and mobile phones – you name it and it’s probably got plastic in it.
That’s also why, when you look for bonding glues for plastics, you’ll find various kinds.Here are a few tips to learn everything you need to know about plastic bonding adhesives:There is no ‘one size fits all’Plastics are characterized by the different kinds of chemicals that go into making each of them.
Each has a different tensile strength, malleability and sturdiness.
This is the reason why one kind of bonding adhesive may not be suitable for all kinds of plastics.Know your plastic before bondingOnce you identify the kind of plastic you are dealing with, it becomes easier to choose the type of adhesive that will be best suited.
PVC can be bonded with a two-part primer and cement, Polystyrene (PS) works well with cyanoacrylates, epoxies or poly cement, and plastics like PET, HDPE, LDPE and Polypropylene (PP) are sometimes quite challenging to bond.Choose according to the applicationWhen you are using plastics in appliances or in plastic assembly, adhesives with low viscosity and less elongation works well, but for lamination or a housing assembly, you might want to choose an adhesive with greater elasticity.
