Soy Flour Substitution in Polymeric Diphenylmethane Diisocyanate Resin Reduces Press Platen Sticking
نویسندگان
چکیده
Abstract Partial (10% to 30%) substitution of soy flour in polymeric diphenylmethane diisocyanate (pMDI) resin substantially reduces platen sticking during hot-pressing particle mats. Adding the a fixed dose pMDI (instead substituting it) an even greater extent. The decreases tack cured pMDI, thereby reducing propensity resinated particles transfer platen. reduction effect on contrasts with its uncured where cold is increased.

متن کاملSensitization and cross‐reactivity patterns of contact allergy to diisocyanates and corresponding amines: investigation of diphenylmethane‐4,4′‐diisocyanate, diphenylmethane‐4,4′‐diamine, dicyclohexylmethane‐4,4′‐diisocyanate, and dicylohexylmethane‐4,4′‐diamine
BACKGROUND Isocyanates are used in polyurethane production. Dermal exposure to isocyanates can induce contact allergy. The most common isocyanate is diphenylmethane diisocyanate used for industrial purposes. The isomer diphenylmethane-4,4'-diisocyanate (4,4'-MDI) is used in patch testing. Diphenylmethane-4,4'-diamine (4,4'-MDA) is its corresponding amine. Concurrent reactions to 4,4'-MDI and 4,...
متن کاملRespiratory hypersensitivity to diphenylmethane-4,4'-diisocyanate in guinea pigs: comparison with trimellitic anhydride.
Published evidence demonstrates successful induction and elicitation of respiratory hypersensitivity in guinea pigs by the known human respiratory allergens trimellitic anhydride (TMA) and diphenylmethane-4,4'-diisocyanate (MDI). From these data it is apparent that TMA-related respiratory hyperresponsiveness can be elicited readily in guinea pigs upon inhalation challenge with the free chemical...
متن کاملThe outcome of 9 years of consecutive patch testing with 4,4'-diaminodiphenylmethane and 4,4'-diphenylmethane diisocyanate.
BACKGROUND Two outbreaks of allergic contact dermatitis caused by isocyanates at two companies in southern Sweden initiated a research project focusing on contact allergy to isocyanates. Within the project, there was an interest in determining how often contact allergy to the most common isocyanate, diphenylmethane-4,4'-diisocyanate (4,4'-MDI), occurred. OBJECTIVES To determine and compare th...
متن کاملPermeation tests of glove and clothing materials against sensitizing chemicals using diphenylmethane diisocyanate as an example.
Diphenylmethane diisocyanate (MDI) is a sensitizing chemical that can cause allergic contact dermatitis and asthma. Protective gloves and clothing are necessary to prevent skin exposure. Breakthrough times are used for the selection of chemical protective gloves and clothing. In the EN 374-3:2003 European standard, breakthrough time is defined as the time in which the permeation reaches the rat...
