“…And the PCL based elastomer had higher tanδ value than the PTMG based elastomer at the temperature around zero centidegree. Based on the time-temperature superposition principle, a conclusion can be made that the PCL based elastomer exhibits good wet skid resistance, low rolling resistance and outstanding dynamic application properties [45,46,47].…”

A series of three cast polyurethane elastomers were prepared from 2,4-toluene diisocyanate (TDI) and 3,5-dimethyl-thioltoluenediamine (D MTDA) chain extender, with polyethylene adi-pate (PEA), polyoxytetramethylene glycol (PTMG) and polycaprolactone (PCL) soft seg-ments. The polyol molecular weights em-ployed was 2000g/mol. The polyurethane elastomers were characterized by an elec-tronmechanical universal testing machine, an Akron abrasion loss tester, a LX-A Shore du-rometer, a rebound resilience equipment and a Dynamic- Mechanical analyzer. In addition, fractured surface of the polyurethane elas-tomers was investigated by a field emission scanning electron microscopy (SEM). The test results showed the PCL based elastomer ex-hibits the excellent tear and stress-strain properties that polyester based elastomers offer, while retaining superior compression set and resilience similar to polyether based elas-tomers. The static and dynamic properties of the PCL based elastomer were more suitable for dynamic applications. The SEM micro-graphs of all polyurethane samples indicated the existing of the microphase separation structure. Particles of the dispersed phase formed by the hard phase and crystalline part of the soft phase grows bigger with the in-creasing crystallinity of the soft segments. The hard domains are irregular shapes and with the sizes of a few micrometers

“…Untuk mengatasi kekurangan ini, sistim penguat adhesi (adhesionpromoting system), seperti resorcinol-formaldehyde latex dan polysocianates telah lama digunakan untuk membentuk lapisan (coating) pada permukaan tekstil untuk meningkatkan adhesi pada permukaan antarmuka tekstil dan karet. Secara umum lapisan adhesive membentuk lapisan antara tekstil dan karet sehingga ada dua lapisan antarmuka yaitu karetadhesif dan adhesif-tekstil yang terjadi pada satu tempat/lokasi [2]. Peningkatan adhesi tergantung pada kondisi variasi dari perendaman dan karet matrix yang digunakan pada pembuatan.…”

Rubber hoses or floating pipe are used mainly in oil and dredging industries. For its use, floating pipe may have good elasticity, strength, water proof, oil resistance, hot resistance and bending resistance. However, in its manufacturing, floating pipe needs several good materials, one of them is textile material as reinforcement material that consists of fibres. From this research, nylon fibre can act best as reinforced textile either as single yarn or fabric form for manufacturing hoses. In manufacturing of hose, however, bonding between nylon and rubber is necessary to receive heavy load during operational, therefore it needs adhesive that joint between nylon and rubber. From test result found that floating pipe made by BPPT has fulfilled the standard for oil industry.

“…A better understanding of these mechanisms is, however, necessary to meet the challenging demands of rubber composites for tire applications. The central task of tire research activities is to solve a multiparameter optimization problem, in particular to optimize in parallel rolling resistance, wet grip and abrasion [9][10][11]. From a more fundamental point of view, this means that one has to design rubber composites fulfilling certain requirements regarding reinforcement and dissipation.…”

A comparative study focusing on the visco–elastic properties of two series of carbon black filled composites with natural rubber (NR) and its blends with butadiene rubber (NR-BR) as matrices is reported. Strain sweeps at different temperatures are performed. Filler network-related contributions to reinforcement (ΔG′) are quantified by the classical Kraus equation while a modified Kraus equation is used to quantify different contributions to dissipation (ΔGD″, ΔGF″). Results indicate that the filler network is visco-elastic in nature and that it is causing a major part of the composite dissipation at small and intermediate strain amplitudes. The temperature dependence of filler network-related reinforcement and dissipation contributions is found to depend significantly on the rubber matrix composition. We propose that this is due to differences in the chemical composition of the glassy rubber bridges connecting filler particles since the filler network topology is seemingly not significantly influenced by the rubber matrix for a given filler content. The underlying physical picture explains effects in both dissipation and reinforcement. It predicts that these glassy rubber bridges will soften sequentially at temperatures much higher than the bulk Tg of the corresponding rubber. This is hypothetically due to rubber–filler interactions at interfaces resulting in an increased packing density in the glassy rubber related to the reduction of free volume. From a general perspective, this study provides deeper insights towards the molecular origin of reinforcement and dissipation in rubber composites.
