Which inorganic filler is known for improving the hardness and reducing the cost of plastics in injection molding?
This filler is abundant and affordable, making it a popular choice.
This filler is more about strength enhancement rather than cost reduction.
This is an organic filler, not inorganic.
This is used for its biodegradable properties, not cost reduction.
Calcium carbonate is a widely used inorganic filler that enhances hardness and reduces costs due to its abundance and low price, particularly in polyethylene and polypropylene applications.
What benefit does talc provide in plastic injection molding?
Talc is known for enhancing the structural integrity of materials.
This characteristic is associated with organic fillers like starch.
While talc can improve surface finish, roughness is typically managed by other treatments.
This is not a primary property of talc; conductive fillers like carbon fiber would be used instead.
Talc enhances the rigidity and thermal stability of plastics, making it ideal for engineering plastics like nylon and polyester due to its layered structure.
Which filler gives plastic products a natural wood appearance?
This organic filler is known for providing a wood-like aesthetic.
This filler does not alter the appearance to resemble wood.
Talc improves mechanical properties but does not provide a wood-like look.
This filler focuses on strength rather than aesthetics.
Wood powder is an organic filler that imparts a natural wood appearance to plastic products while also reducing material costs, commonly used in wood-plastic composites.
Which organic filler is biodegradable and helps improve the environmental profile of plastics?
This filler is popular for its eco-friendly properties.
Talc is inorganic and not biodegradable.
Mica enhances electrical properties but isn't biodegradable.
Glass fiber is used for strength, not for its biodegradability.
Starch is a biodegradable organic filler that improves the environmental footprint of plastics by facilitating decomposition, aligning with sustainability goals.
What property does glass fiber primarily enhance in plastics?
Glass fiber is widely used to boost tensile strength and rigidity.
Glass fiber does not contribute to biodegradability.
The focus of glass fiber is on functional rather than visual properties.
Glass fiber actually helps improve thermal stability.
Glass fiber significantly enhances the mechanical properties of plastics, such as tensile and impact strength, making it ideal for reinforced plastic applications.
Which filler has a needle-like structure that improves strength and dimensional stability in high-performance plastics?
This filler is unique for its needle-like fiber structure.
Starch does not have this structural characteristic.
Wood powder provides a natural appearance but lacks this structure.
Talc has a layered, not needle-like, structure.
Wollastonite's needle-like fiber structure enhances the strength and dimensional stability of high-performance plastics such as polycarbonate.
Which filler can potentially roughen the surface of plastic products, requiring post-treatment?
This filler is known for high strength but can affect surface texture.
This filler doesn't typically affect surface smoothness.
Starch impacts processability but not surface texture directly.
Mica enhances insulation rather than affecting surface finish significantly.
Glass fiber can roughen the surface of plastic products due to its fibrous nature, necessitating post-treatment to achieve smooth finishes.
Which filler type is often chosen for its ability to reduce overall material costs while being eco-friendly?
This renewable resource provides both cost and environmental benefits.
Though strong, it is expensive and less eco-friendly.
Talc reduces shrinkage but isn't focused on eco-friendliness or cost alone.
While cost-effective, its eco-friendly credentials are less pronounced than wood powder's.
Wood powder reduces material costs and provides eco-friendly benefits due to its renewable nature, offering a balance between affordability and environmental responsibility.
