A flame-retardant composition endowed with intumescent properties which consists of an acrylic resin, a dehydrating compound, a blowing agent and, optionally, a fluorocarbon-based polymer.

This mixed suspension contains (1) a dispersant, (2) a cellulose nanofiber, and (3) a filler.

Self-fusing silicone tapes contain neutral corrosion inhibitors therein such as salts of acids. Such tapes provide protection in an acid gas environment as well as under thermal insulation. The same also allows inspection of protected structure without removing the protection apparatus.

Disclosed in the present invention is a semiaromatic polyester, a preparation method and application thereof. Having a specific segment length and carboxyl group content, the semiaromatic polyester provides a balance of degradation rate and mechanical properties, compared with known semiaromatic polyesters. The 30-day weight retention of the semiaromatic polyester obtained in the present invention may be contained to from 45 to 70%.

A gel for use in a pH or an ORP sensor, components of the gel comprising water, a reference electrolyte salt, a buffering system for adjusting pH of the gel, and a polymeric gelling agent, and the gel does not degrade under gamma irradiation.

An aqueous binder composition is provided that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a dedusting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats. A method of making fibrous insulation products is also provided.
