Rubber Chemistry Process - We want to make latex tubing,

We have a small facility in rural Thailand. We consume significant amounts of Latex tubing with our own production. We want to make our own Latex tubing because the local supplier's pricing is too high and the quality of imported product is inconsistent. Our intention is simply to make colored latex tubing for our own consumption. We are quite self sufficient and competent, we have resources including space, machine shop and technicians and most of all, interest, we just need a bit of insight on how to convert a locally available raw material into a material which we can use in our sporting goods products. We would like to find a tutor with experience in this field and we can check in with as we progress towards our goal of making colored 4 mm diameter Latex tubing. We posted a small budget for this but can pay more depending upon the support you can bring.
