Medical Grade PVC Compound

Longcheng has always been at the forefront of polymer materials exploring.We have established long-term cooperation with several well-known enterprises abroad for raw material supply,And the DEHP- F ree series especally have been well received. Our products are in two major calegories- PVC series,DEHP-Free series ,which including ten top series such as blood line for hemodialysis,respiratory and anesthesia products,I ight proof infus ion  infusion set,etc.Our new project is committed to providing all customers w ith a comprehen-sive combination of material and technology,research and development,production technical service,aiming at becoming a leading enterprise in the medical polymer materials industry with global competitiveness,and escorting for products Made in China going global.

​

Dehp Type Pvc Field

The applications of PVC compound include disposable infusion (liquid) equipment or precision transfusion (liquid) appliances,light-proof infusion set,hemodialysis series,anesthesia and respiratory circuit series,nutrition bags,blood bags,suction tubes,and Yanke tube.

With the increase of population aging and the rising of chronic diseases,the medical services market has continued to grow.Medical PVC compound has gradually become one of the important raw materials for medical supplies and equipment.

In particular,since the 21st century,kidney disease has become one of the major hazards of human health,and hemodialysis is the current and the next few decades of end-stage renal disease (uremia) the main means.Hemodialysis therapy equipment is made up by the dialysis machine,dialyzer,blood circuit and other components,including dialysis and blood circuit for medical plastic made of medical supplies.

After years of efforts,China's medical plastics industry is gradually to the high-tech,high-end,high-quality direction,product upgrading,industrial upgrading significantly.Many companies launched needle,PTCA,Strengthen the catheter intubation,analgesic pumps and various types of anesthesia supplies products,etc.; these enterprises will inevitably bring about the upgrading of China's medical plastics industry to enhance.

​

Non-phthalates Type Pvc Field
Bis (2-ethylhexyl) phthalate,referred to as DEHP or DOP,is the most commonly used plasticizer in PVC process.Throughout the world of medical PVC products,it has been clearly not allowed to add 17 kinds of phthalates as plasticizers.

A large number of experiments at home and abroad proved that phthalates into the human body and animal body will have similar estrogen role,will interfere with endocrine,is a potential endocrine disruptors.At present the EU has banned toys containing DEHP ingredients.

Although the exposure time of infusion device in the infusion process is short,and medical PVC DEHP addition ratio is less,in order to maximize the safety of each infusion device users, non-phthalates type PVC material came into being.We have started to sell this product since 2008,and the initial major customers are European and American manufacturers.Since

October 20 12 the domestic medical device industry give great importance to the potential risk of DEHP,we help customers to produce,and register non-phthalates PVC infusion device.

Longcheng provides the opportunity to choose right plasticizers in order to help customers find the most suitable for their own products.

​

NON-DEHP plasticizer has a higher biosafety than DEHP.It is widely used in Europe and the United States,Japan and South Korea market.Applications include the blood transfusion (liquid) equipment,blood purification products,respiratory anesthesia products.It is a better alternative to raditional DEHP products.

Application

We offer different NON-DEHP plasticizers according to customer's needs:

1 TOTM type

Widely used in blood transfusion (liquid) equipment category.

2 DINCH type

Concerning on the protection of red blood cells,more suitable for blood purification products.

3 DOTP type

Better plasticization,more cost-effective.

4 ATBC type,DINP type,DOA type

Widely used in connection and suction tubes.
