چکیده
There is an inevitable trend toward exploring new, environmentally friendly fibers that can be used as raw material for mattresses with moderate hardness and air-permeable characteristics. Ethylene-propylene side by (ES), high-shrinkage fibers, thermoplastic polyester elastomer (TPEE) chips were introduced into polyethylene glycol terephthalate (PET)/polybutylene (PBT) chip melt blending to modify PET/PBT fiber. The modified (hereinafter referred PLON) more suitable mattress filling than PET/PBT. To explore the compressive properties of PLON cushion made fiber expand scope cushion’s application, a layered test, classification test variance analysis comprehensively evaluate surface hardness, core bottom cushion. conclusions are: (1) materials support layer have significant effect on grade S. between spring coir; (2) when layer, it possesses higher supporting force coir characteristics light weight high resilience, which does not have; also softer mattress. As material, provides foam. Practical applications, densities structure clarified through above research, implications broader applications blocks in products.

The purposes of this investigation were 2-fold: to study the physical properties and sealing ability of Viscosity Enhanced Root Repair Material (VERRM); and, to compare them with Mineral Trioxide Aggregate (MTA). VERRM has a composition similar to mineral trioxide aggregate, with handling characteristics and consistency similar to commercially available materials such as IRM and Super EBA. The ...
متن کاملCompressive properties of commercially available polyurethane foams as mechanical models for osteoporotic human cancellous bone
BACKGROUND Polyurethane (PU) foam is widely used as a model for cancellous bone. The higher density foams are used as standard biomechanical test materials, but none of the low density PU foams are universally accepted as models for osteoporotic (OP) bone. The aim of this study was to determine whether low density PU foam might be suitable for mimicking human OP cancellous bone. METHODS Quasi...

The objective of this research is to study the effects of myofiber volume fraction and fiber orientation on the deformation mechanics of left ventricular (LV) during diastole. The human LV was simulated by three-dimensional finite element (3D-FE) model. The LV geometrical model was represented as a thick-walled ellipsoid truncated at two thirds of major axis. 3D Fiber network, with parallel myo...
متن کاملPhysicochemical and biological properties of a novel injectable polyurethane system for root canal filling
A root canal sealer with antibacterial activity can be efficacious in preventing reinfection that results from residual microorganisms and/or the leakage of microorganisms. In the present study, a series of injectable, self-curing polyurethane (PU)-based antibacterial sealers with different concentrations of silver phosphate (Ag3PO4) were fabricated. Subsequently, their physicochemical properti...
