“…The attractive properties of NR Latex includes its excellent elasticity (ability to stretch many times from its original length without creating holes or breaches), flexibility, have antivirus protection and biodegradable 1 . These excellent properties offers NR Latex as a versatile material in different products applications such as dipped goods 2 , extruded threads 3 , blood transfusion tubing catheters 4 and adhesives 3 . Despite its good performance, significant research is directed at using biodegradable fillers such as starch 5 , banana fibers 6 , oil palm 7 and chitosan 8 to place common filler used such as carbon black, silica and synthetic fibers.…”

This research discussed the influenced of different preparation methods of Carrageenan fillers as new natural biodegradable additives in Natural Rubber (NR) latex compound. NR latex compounds with addition of 2 phr Carrageenan fillers was prepared through normal pre-vulcanization method which the NR latex compound was subjected to 70 o C denoted as Method 1. The preparation of NR latex compounds with 2 phr Carrageenan fillers without temperature is denoted as Method 2. The unfilled NR Latex films also was prepared as a control through Method 1. The crosslink density and mechanical properties of NR Latex films were investigated via swelling test and mechanical testing (tensile and tear) respectively. The swelling test results shows that Method 2 have highest crosslink density where the crosslink density and mechanical properties via Method 1 shows a decreased value. This may contribute from the hydration of carrageenan at temperature of 40 o C-70 o C. The experimental results indicate that the addition of carrageenan with elimination of pre-vulcanization step is mainly responsible for the enhancement of crosslink density and mechanical properties compared to Method 1. Method 2 gives higher crosslink density, tear strength and lower modulus as evaluated from the mechanical properties. Carrageenan can be added as natural filler in NR Latex films with gives better interaction between rubber matrix and fillers with softer NR latex films which required in NR latex products especially gloves.

“…There is no prior documented case of testing such technology in space conditions (microgravity and vacuum). Industrial jamming grippers might work with negative (down to -0,85 bar) and positive (up to 6,2 bar) pressures [4] to increase gripping forces. It is not possible to mimic this approach in a vacuum.…”

TRACZ -Testing Robotic Applications for Catching in Zero-g is a fully autonomous mechatronic experiment, launched on March 19, 2019, on board the REXUS rocket, during the 26th Campaign of the REXUS/BEXUS Programme. The main goal of the experiment was to investigate the jamming phenomenon in the space environment (microgravity and vacuum) as well as to construct a version of industry device known as jamming gripper, capable of operating in conditions where negative pressure (physical basis of operation in Earth-like conditions) cannot be obtained due to the presence of only a residual atmosphere. The structure was designed as 1-DOF manipulator, whose effector is an elastic membrane that stimulates jamming of ground coffee particles inside. During the suborbital flight, a series of catcheswere performed on a single object and the force with which the object is held was measured. The results were compared with an on-ground experiment.

“…In this process, a foamed latex mixture freezing is in the molds. 2 -5 In this method, the mechanically foamed blend of natural and synthetic rubber latex and additives fills the hermetically closed mold to a certain height. Then, due to the vacuum created in the mold, the foam fills it completely.…”

This work presents an innovative method for producing porous castings from polymer dispersion with wood flour. The method described for forming porous castings from blends, in which the aqueous dispersions of polymers are binders, enables the manufacturing of wood-like products with a cork-like structure. The casting technology and selected properties of finished castings (density, compression strength) are presented. The structurual investigations of the obtained castings are also presented.
