The present invention relates to a sizing composition for mineral fibers, especially glass fibers or rock fibers, containing a liquid phenolic resin having a free formaldehyde content, expressed with respect to the total weight of liquid, of 0.1% or less and an extender. Preferably, the liquid phenolic resin is mainly composed of phenol-formaldehyde and phenol-formaldehyde-amine condensates and has a water dilutability, at 20 C., at least equal to 1000%. Another subject of the present invention is the insulating products based on mineral fibers treated by said sizing composition.

An extruded composite adapted for use as a building material includes a core having a base polymer and a natural fiber in a substantially homogeneous mixture and an ionomer capstock. To improve adherence of the ionomer to a base polymer, the ionomer can be mixed with a similar or substantially similar base polymer prior to coextrusion with the core. Additionally, various additives may be mixed with the capstock material to improve visual aesthetics of the product and performance of the building material, especially over time.

An oyster paper and a manufacturing method thereof are provided. The oyster paper is made of 60%-70% oyster shell powder, 10%-20% polymer, 15%-17% natural biodegradation inducing agent, and 3%-5% natural biodegradation assisting additive agent, by volume ratio, which are subjected to mixing and pre-melting processing, followed by compounding and pelletizing to prepare oyster paper pellets, which are then subjected to film blowing processing to be film-blown into an oyster paper product having a thickness of 0.05-0.5 millimeters. The oyster paper possesses the quality of wood pulp paper and shows bettered stiffness and wider applications. The oyster paper also provides, after being disposed and buried, an effect of being 100% natural degradation into compost for fertilizing the soil. As such, a kind of oyster paper featuring recycling and reuse of oceanic creature waste shell and natural microorganism induced degradation for composting and recycling and a manufacturing method thereof are provided.
