MMA Grafted Natural Rubber Latex

Manufacturer: We heard of some latex products manufacturers using grafted Natural Rubber latex. Can you tell us more about this?
John Woon (Senior Latex Consultant): Many research works have been done on graft polymerisation of many monomers on natural rubber latex. However one monomer that is being used for commercialisation of the grafted latex is methy methacrylkate.
The level of polymethy methacrylate is usualy about 50%, although other levels could be used. The main applications of grafted NR latex are in aghesives and as reinforcing agent especially for tear stregth, modulus, stiffness and abrasion resistance.
You could purchase this from Revertex Malalysia Sdn Bhd. Thier product is trade named Graftex 49 with 49% of PMMA.

You are at the site for answers and solutions to all your problems in natural rubber latex processing and manufacturing of industrial, household and medical gloves, condoms, catheters, baby teats and baby pacifiers, toy balloons, latex foam products, latex threads etc.

CISSP Training for IT Security Professionals

Sophisticated security software, regular security assessments and stringent security policies alone cannot ensure good information security standards in an organisation. It requires the personnel to be well trained, updated and knowledgeable about information security aspects. Professional trainings and certifications play a significant part in the continuous development of IT professionals.
The 2015 (ISC)2 Global Information Security Workforce Study clearly shows that the information security workforce shortfall is widening. In the 2015 survey, 62% of the survey respondents stated that their organizations have too few information security professionals compared to 56% in the 2013 survey.
To fill the workforce void in Information Security, having the right certification matters. There are a variety of certifications to choose from in the field of Information Security, so which one is the best fit for you?

Some Of The Testimonials Received by John Woon Latex Consultants: __________________________ ------------------------------------------------------------------------------------------------------------------------------------ ---------------------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------------- 1) My name is Ugan Padayachee, a South African Mechanical Engineering student (Durban University of Technology) I am deeply indebted to Mr. Woon for the personal assistance he provided me during my latex research. I have no experience with chemistry and was assigned the task of developing a latex bag as part of my training. I asked many students and lecturers for assistance but no one was prepared to sacrifice their personal time. The internet was basically my only source of information. It took me months to create a product which resembled a bag, which was far from complete. I was on the verge of giving up when I stumbled across Mr. Woon's website which I immediately emailed. I firmly believe that Mr. Woon is an invaluable mentor. It is rare finding professional people such as Mr Woon who offers expert services to students and others. Mr. Woon made it his honourable duty and an effort to reply to all of my emails as promptly as possible, and provided me with a detailed professional analysis. This obviously resulted in an immediate success in my project. I greatly appreciate the time and valuable advice that he offered me. Although I did not personally meet Mr. Woon, I strongly believe that he is a man driven by passion and love for helping others. His expertise in his field of Latex Technology is highly recommended to anyone seeking advice.

2) We are medical glove manufacturer. It gives me great pleasure to write this testimonial to express our utmost and sincere thanks to Mr. John Woon for guiding us towards achieving the present very high production yield and away from the nightmares we used to have. His simple step-by-step approach in explaining our problems and recommending the various steps we need to carry out is so easy to follow especially by our factory workers. Our only regret was that we did not "discover" him earlier than our competitors! We wish him all the best and hope that he’d continue to help us whenever we need him.

3) We have been making toy balloons of all types for many years. Our recent encounter with Mr.Woon was very fortunate for us. Our productivity has now improved and customer complaints have reduced. We’re very grateful to this very experienced latex technologist and would recommend his service to anyone without hesitation.

4) Great job, Mr. Woon and many thanks to you for your very valuable information and advice. You’re most welcome to our factory anytime.

5) First of all let me say this, John: My supervisors hope that you could be with them everyday! You’ve solved their many problems and the best thing about this was the way you explained to them in very simple layman language that they could easily understand!
6) Pardon my English. I only speak and write Spanish with only very little English but I could understand you well. Mucho gracious amigo for all the help! If you want in Spanish, I write more.

7) Your advice on the right choice of accelerators has overcome our persistent blooming problem and also problem of detergent resistance of our household gloves which we had for a long time. When can you visit us? We want to have you as our guest.

8) We have been attacked by over cured latex compounds on many occasions. Our balloons and glove suffered high loses because of tearing. Mr. Woon came to our rescue through a friend. Our fees to him could not reflect our gratitude. We hope we could meet him one day!

9) John, I have such faith in your system. Anyone can take a full 8 weeks to check your report on recommended remedial actions. Put it to work in his factory that produce any latex dipped products. If he cannot solve at least some of their daily problems using your strategies and techniques, he should come to me and I’d show him what I’ve learnt from you! In the incredibly unlikely event that he still doesn’t make any headway, I’d volunteer to pay him the money that he has invested in your report!
10)John was extremely helpful in explaining the chemistry and processes involved in latex reactions. His knowledge and expertise helped a great deal in a specific problem which we were trying to overcome. Not only did John explain the reactions that could be occuring, he also suggested possible products to include into a formulation which would aid the performance of the final product.------------------------------------------------------------------------------------------------------------------------------------

12) We located John Woon’s website while searching for an answer to our coagulant mixing problem. Within a matter of hours we had the answer we had been searching for weeks to find. Not only that, but he helped locate the supplier of what we needed. Fast, efficient expert advice, what more can you asks for.
13)I’m very pleased to write this brief testimony after John Woon had successfully guided us in our rubber compound formualtion for an application that requires very high heat resistance and low tension set. We were amazed by his very easy to follow instruction written in simple English so that our supervisors amd factory floor workers could understand.
