Rubber is a polymer that is classified into two types, namely, natural rubber and synthetic rubber. Natural rubber is extracted from latex, which is a milky fluid emanating from the bark of rubber trees, while synthetic rubber is manufactured through chemical processes. The rubber is processed using various chemicals to improve its resistance to heat, sunlight, oxidation, ozone, and mechanical stress. Rubber processing chemicals are also an integral component used for vulcanizing rubber. They are classified into different groups based on their functions. The different types that are mainly used are antidegradants, accelerators, processing aids, anti-scorch agents, blowing agents, polymerization regulators, and shortstops.

A micromechanics analysis modeling method was developed to analyze the damage progression and fatigue failure of fabric reinforced composite structures, especially for the brittle ceramic matrix material composites. A repeating unit cell concept of fabric reinforced composites was used to represent the global composite structure. The thermal and mechanical properties of the repeating unit cell were considered as the same as those of the global composite structure. The three-phase micromechanics, the shear-lag, and the continuum fracture mechanics models were integrated with a statistical model in the repeating unit cell to predict the progressive damages and fatigue life of the composite structures. The global structure failure was defined as the loss of loading capability of the repeating unit cell, which depends on the stiffness reduction due to material slice failures and nonlinear material properties in the repeating unit cell. The present methodology is demonstrated with the analysis results evaluated through the experimental test performed with carbon fiber reinforced silicon carbide matrix plain weave composite specimens.

Lyocell is a manufactured fiber that is derived from cellulose. Lyocell fiber is manufactured through a solvent spinning technique by the closed loop method, where cellulose experiences a chemical change. Lyocell fibers are widely used in textiles. Although lyocell is manufactured it is a natural fiber because it is made from wood pulp. Lyocell fiber is the strongest cellulose fiber when dry and known for its property of durability.

Specialty pressure-sensitive tapes adhere to surfaces when pressure is applied and do not require solvents, heat, or other agents. These tapes are used in industrial and construction applications because of their high-tensile strength. They are also used in the healthcare and automotive industries for their fastening and bonding properties. Many variants of these tapes, such as double-sided tapes, are available in the market.

A membrane is a type of selective barrier that is used to separate or concentrate the feed stream as it passes through the membrane, which selectively allows some constituents to pass as others are retained on the surface of the membrane. The constituents that are allowed to pass are known as permeates and those that are retained are known as concentrates or retentates. Different types of membrane are used in the Food industry depending on their pore size. The types of technology implemented for membranes include ultrafiltration, microfiltration, reverse osmosis, and nanofiltration. Other membrane technologies such as membrane contractors, electro dialysis, and pervaporation are also used but their market share is low.

RO is a technology that uses a semipermeable membrane to remove dissolved salts or organic molecules. The water is pushed using a high-pressure pump through the membrane and allows the passage of water molecules but prevents dissolved salts and bacteria from passing through. The pump capacity required for the process depends on the salt concentration of the feed water. The semipermeable membrane used for the process is mainly made of two materials: cellulose acetate and an aromatic polyamide. In addition, the RO membranes fall into two categories – Asymmetric membranes and thin film composite membranes. While asymmetric membranes contain one polymer, the thin film composite membranes contain two or more polymer layers.

Stretch and shrink films are used for packaging and protecting goods from damage and spoilage. As these highly engineered polythene films have special chemical properties, they differ from one another in terms of their flexibility and stretchability. Stretch films are thin elastic polythene films that are used to wrap around pallet loads, while shrink films are thin films that are used to wrap around a single product or commodity and require heat for packaging.

Adult diapers are necessary for people suffering from conditions such as urinary or fecal incontinence, mobility impairment, or dementia. The convenience and comfort offered by adult diapers has increased their acceptance among people. The disposable diaper technology has been evolving since the 1970s, and adult diapers are a comparatively recent innovation. The production of adult diapers is a multi-step process in which the absorbent pad is vacuumformed and attached with elastic fibers.

Adsorbents are materials that have the ability to adsorb fluids and dissolved solids onto their surface. Adsorbents work by creating a layer of adsorbate onto the surface through adhesion. They are used for various industrial applications, including process industries, water purification, and air separation. Adsorbents are of various types and can be broadly classified into zeolite, activated carbon, silica gel, alumina, clay, and metal oxide and others. Adsorbents are increasingly being used to reduce contamination in both air and water during various industrial processes.
