Para Rubber Taxonomic C l a ssification Class : Angiospermae Subclass : Dicotyledoneae Order : Euphorbiales Family : Euphorbiaceae Genus : Hevea Species : brasiliensis Scientific name : Hevea brasiliensis Muell Arg. Common name : Para Rubber
HDPE is the high density version of PE plastic . Because it has little branching , giving it stronger intermolecular forces and tensile strength than lower density polyethylene . So It is harder, stronger, more opaque and a little heavier than LDPE, but less ductile . HDPE
HDPE HDPE is lighter than water, and can be moulded and joined together HDPE is resistant to many different solvents and has a wide variety of applications
Objective To study about appropriate ratio to produce particle board from Para rubber wood flour, coconut flour, and recycled plastic.
