Steps in making silicone items

Image
  STEPS IN MAKING SILICONE PRODUCTS  There are three main steps in making a silicone product, first, you need to make the mold, then cast the silicone using the mold you have just made, and the last step is to paint the silicone product.      This is a video on making a mold out of resin  The next video is on how to cast silicone prosthetic mask /make-up   For those of you who would like to do a DIY silicone item, here is the silicon package found on amazon. Inside the box, there will be two parts A and B, the thick one is the silicone and the clear liquid is the catalyst. You only need to mix part A and B with 1:1 ratio.    Click here to buy    

Rubber-like material Silicone

  Silicone is a polymer containing silicon together with carbon, hydrogen, and oxygen. Silicone and rubber are both elastomers (rubber-like material). Silicone will appear matte compare to latex which will appear glossy/ shiny.   Silicone can be used in the making of molds, usually for craft or baking purposes   Silicone also can be used in the making of products that mimic a lifelike human, or as the extension of the human body, or prosthetic,  as seen in these pictures below lifelike/ realistic reborn baby doll Silicone man chest Silicone man bodysuits lifelike/ realistic prosthetic Silicone for prosthetic makeup effect 

Rubber Latex vs Silicone

Image
  If you have seen my previous posts about latex and silicone, you will notice that both of them can be used to make prosthetic. You might be wondering what is the differences between the two.  Based on my experience, latex is cheaper than silicone. Additionally, they are both a two parts packages, meaning there will be part A + part B that have to be mixed together. I found this video online with a side by side comparison between the two, enjoy       

Rubber in Movies

Image
  As I mentioned before, there are many types of rubber, such as  natural rubber (natural latex), and  many types of synthetic rubbers. Synthetic rubber will include Styrene-butadiene rubber (SBR), synthetic latex.   Moreover, also can be found rubber-like materials such as silicone rubber, PVC rubber. In movies or music videos, latex usually is used as the material for the costume, such as t he catsuit wore by Michelle Pfeiffer in the 1992 Catwoman movie.   Carrie Anne Moss in the Matrix 1999 Britney Spears in Oops I did it again music video Moreover, latex also can be used for a prosthetic. For example, the prosthetics for the 1939 Wizard of Oz movie which were made of foam latex.  A prosthetic was created for the 1994 production of The Mask starring Jim Carrey. This item is made from foam latex  

Rubber Household Items

  There are many types of rubber, such as natural rubber (natural latex), and  many types of synthetic rubbers. Synthetic rubber will include Styrene-butadiene rubber (SBR), synthetic latex.   Moreover, also can be found rubber-like materials such as silicone rubber, PVC rubber. So many household items being made of rubber such as rubber bands, rubber gloves, pond liners,  grips on garden tools, bathtub plugs, doorstops, earplugs, aquarium tubing, faucet washers, and rug backings. Other household items which are made of rubber are  Rubber Eraser Latex Condoms  Latex gym/ exercise ball Latex Flipper Rubber/ Latex Swimming Cap Latex Pacifier  Latex Hot water bottles Modern balloons are made from a liquid rubber called latex. Before 1824, early balloons were made from dried animal bladders.

The Making of Rubber

Image
There are two types of rubber, the natural one and a   synthetic one . Let's start with the natural one, a  n atural rubber is taken from a rubber tree called H evea Brasiliensis.  Hevea Brasiliensis  is a species of rubberwood that is native to rainforests in the Amazon region of South America, including Brazil, Venezuela, Ecuador, Colombia, Peru, and Bolivia. These trees are  generally found  in low-altitude moist forests, wetlands, riparian zones, and forest gaps.  Natural rubber  is extracted by a method called tapping, by  making  incisions into the bark and collecting the fluid into vessels attached to the  rubber  trees. The liquid is a sticky, milky sap called latex, and requires a couple of steps before it will be sold as  natural rubber Here's a video of getting a rubber tree ready to be tapped Another video for an all-through process   In contrast, synthetic rubber such as P olymers is  made  from...

History of Rubber

Image
  THE TIMELINE OF RUBBER The first use of rubber was by the indigenous cultures of  Mesoamerica . The earliest archeological evidence of the use of natural latex from the  Hevea tree  comes from the  Olmec  culture, in which rubber was first used for making balls for the  Mesoamerican ballgame .  Rubber was later used by the  Maya  and  Aztec  cultures – in addition to making balls Aztecs used rubber for other purposes such as making containers and to make textiles waterproof by impregnating them with the latex sap. In 1770 English engineer Edward Nairne is reported to have developed the first widely marketed rubber eraser, for an inventions competition. Nairne sold natural rubber erasers for the high price of three shillings per half-inch cube. However, the raw rubber was perishable. In 1839 Charles Goodyear discovered the process of vulcanization, a method that would cure rubber, making it durable. Rubber erasers became ...
