Retrobright 1970-01-01
Retrobright is a chemical process used to restore the original color of yellowed or discolored plastics, particularly those found in vintage electronics and computers. Over time, certain types of plastic, especially those made from ABS (acrylonitrile butadiene styrene), can turn yellow or develop a brownish tint due to exposure to ultraviolet (UV) light, heat, and other environmental factors.
Ripstop polyester 1970-01-01
Ripstop polyester is a type of fabric made from polyester fibers that have been woven in a special grid pattern to enhance its durability and resistance to tearing and ripping. The term "ripstop" refers to the technique used in the weaving process, where thicker threads are interwoven at regular intervals throughout the fabric. This structure helps prevent small tears from spreading, making the material highly resilient. Ripstop polyester is commonly used in various applications due to its lightweight nature, strength, and water-resistant properties.
Rope caulk 1970-01-01
Rope caulk, also known as rope caulk tape or rope sealant, is a type of weatherproofing material commonly used to seal gaps, cracks, and joints around windows, doors, and other areas in buildings to improve energy efficiency and reduce air leaks. It is typically made from a flexible, pliable material such as foam or a similar substance, often encased in a protective layer.
Rubber toughening 1970-01-01
Rubber toughening is a process used to improve the toughness and impact resistance of brittle materials, particularly polymers and thermosetting resins. The technique involves the incorporation of rubber particles into a polymer matrix. When these rubber particles are blended with the polymer, they act as "toughening agents," which can absorb and dissipate energy during impact, thereby preventing crack propagation and failure.
Saran (plastic) 1970-01-01
Saran is a brand name that is often associated with a type of plastic wrap or food film used for covering and preserving food. It is made from a polymer called polyvinylidene chloride (PVDC), which has properties that make it effective for stretching and sealing around various food items. Saran wrap is known for its ability to cling tightly to surfaces, which helps to create an airtight seal that keeps food fresh by preventing moisture and air from getting in.
Silverstone (plastic) 1970-01-01
Silverstone is a brand of high-performance non-stick coating used in cookware, particularly in frying pans, pots, and bakeware. It is known for its durability and resistance to scratching and staining. Silverstone coatings are often made from polytetrafluoroethylene (PTFE), commonly known as Teflon, but may also incorporate additional materials that enhance their non-stick properties.
Solvent bonding 1970-01-01
Solvent bonding is a process used to join two or more plastic components by softening their surfaces with a solvent. This technique is commonly employed in the assembly of thermoplastic materials, such as acrylic, polycarbonate, and PVC. Here's how it works: 1. **Surface Preparation**: The surfaces of the components to be bonded are cleaned to remove any contaminants that could affect adhesion. 2. **Application of Solvent**: A solvent is applied to the surfaces of the plastics involved.
Splay (plastics) 1970-01-01
Splay, in the context of plastics, refers to a defect that can occur during the injection molding process. It manifests as a flow pattern or streak in the finished molded part, often caused by the flow of the molten plastic during processing. Splay can result in an unsightly appearance and may impact the mechanical properties of the final product.
Squeeze flow 1970-01-01
Squeeze flow refers to a type of deformation behavior observed in materials, particularly in soft materials such as polymers, gels, and biological tissues. It involves the compression of a material in such a way that its shape changes under an applied pressure without significant lateral displacement. This flow mechanism is often studied in the context of rheology, which is the science of flow and deformation of materials. In a squeeze flow test, two plates are typically used to compress a sample of the material.
Styrene-acrylonitrile resin 1970-01-01
Styrene-acrylonitrile (SAN) resin is a type of thermoplastic polymer that is produced by the polymerization of styrene and acrylonitrile monomers. It is a copolymer, meaning it consists of two different monomer units, which gives it unique properties that make it suitable for various applications. ### Key Properties: 1. **Transparency**: SAN can be produced to be highly transparent, making it a good substitute for glass in certain applications.
Surface treatment of PTFE 1970-01-01
Surface treatment of PTFE (Polytetrafluoroethylene) refers to various processes applied to modify the physical or chemical properties of PTFE's surface to enhance adhesion, improve wettability, increase surface energy, or modify friction characteristics. Because PTFE is known for its low surface energy and non-stick properties, it can be challenging to bond it with other materials or to apply coatings.
Synthetic resin 1970-01-01
Synthetic resin refers to a group of man-made polymers that are used as a plastic matrix in various applications, including adhesives, coatings, and composite materials. These resins are not derived from natural sources but are created through chemical processes involving the polymerization of monomers. There are several types of synthetic resins, including: 1. **Thermoplastics**: These resins can be melted and reformed multiple times.
Thermoplastic 1970-01-01
Thermoplastics are a type of plastic material that becomes moldable upon heating and solidifies upon cooling. This process can be repeated multiple times, allowing for recycling and reshaping without significantly altering the material's properties. Key characteristics of thermoplastics include: 1. **Reversibility**: They can be melted and reshaped repeatedly, making them versatile for various applications.
Timeline of plastic development 1970-01-01
The timeline of plastic development outlines the key milestones in the creation and evolution of plastics from the 19th century to the present. Here’s a summary of major events and innovations in the history of plastics: ### 19th Century - **1830s**: The first synthetic resin is created by Scottish chemist Alexander Parkes, who unravels a material he calls "Parkesine," derived from cellulose.
