Avaliação do teor dos aditivos estabilizantes e das propriedades mecânicas em compostos elastoméricos para lateral de pneu de passeio submetidos ao envelhecimento natural e acelerado
(2015-02-11)
This study aims at analysing the ideal rate of two stabilizers in elastomeric compounds, used in tires that require a long-term performance, submitted to different kinds of aging. The resistance to the aging can be achieved ...
Influência da combinação sílica/negro de fumo e das etapas de processamento no desempenho de bandas de rodagem de pneu de carga
(2015-08-18)
One of the major challenges in the rubber industry today is related to the relationship between durability, safety and economy for tire applications. Important progress on rolling resistence reduction with good wet grip ...
Desenvolvimento e caracterização de compósitos de elastômero termoplástico de poliuretano (TPU) com argila
(2015-10-07)
In this study thermoplastic polyurethane (TPU) composites were obtained with different nanoclay contents (0, 1, 3 for all cases and 10 wt% in some cases). The nanoclay Cloisite 30B (C30B) was dispersed in the TPU matrix ...
Síntese e Caracterização de elastômeros microcelulares de poliuretano
(2014-05-13)
In this work, three different microcellular polyurethanes elastomers (EMPU) based on 4,4-diphenylmethane diisocyanate (MDI) with different rigid phase contents were prepared (Formulations 1, 2 and 3 with 32, 35 and 42% of ...
Estudo da influência de resinas de tack em formulações elastoméricas e metodologias de avaliação aplicadas
(2022-09-20)
The present work aimed to evaluate the influence of different types of tack resins in elastomeric formulations, as well as to develop a simple, robust and reproducible test methodology to evaluate the tack of these elastomeric ...
Avaliação da influência da mistura de elastômeros nas propriedades físico-químicas e mecânicas de formulações elastoméricas
(2023-11-07)
This study aimed to evaluate the influence of the mixture of different polymers such as natural rubber ((poly(cis-2-methyl-buta-1,4-diene)) (NR), styrene-butadiene copolymer (poly(buta 1,3-diene-co-styrene)) (SBR) and ...
