Mar , Mycotoxins are secondary toxic metabolites produced by the fungal mold organisms They are similar to bacteria metabolic (feeding) byproducts, which can be more toxic than the bacteria itself Some mycotoxins are actually far more toxic than more common toxins such as heavy metals and pesticides.
Vacuum assisted resin transfer molding (VARTM) has also grown over the past few years to include the fabrication of large composite structures for the marine industry, as well as secondary structures for military aircraft, such as engine inlet ducts In VARTM the liquid resin is infused into the preform by pulling a vacuum on
Finally, the invention provides methods of using the chain extenders to improve the properties of virgin, recycled, and reprocessed condensation polymers including polyesters, polyamides, polycarbonates, and polyurethanes are widely used to make plastic products such as films, bottles, and other molded products.
Techniques for creating recycled plastic materials from waste plastic materials are described A recycled plastic material contains at least a primary polymer, a secondary polymer, and residual additives Predetermined properties of the recycled plastic material can be controlled by selecting the types of waste plastic
Mar , To help solve these problems, plastic recycling programs have been instituted in many countries Conventional thermoplastics can be molded and then melted again, but thermoset plastics form bonds between polymers strands when cured, creating a tangled matrix that cannot be undone without
A number ranging from to inside a recycling symbol has been assigned by the SPI to each of the major plastic resin types and that number is molded onto each It is hypothesized and partially proven that the issues of drying, cleanliness, compatibility, surging and the like that are important for most secondary recycling
