What more expensive plastics can an upgraded HIPS beat?

Did you know? HIPS is a unprocessed piece of jade. Judging from the feedback of no less than 20 customers in recent years, the HIPS with the skill patch package is not only capable of ABS operating conditions, but can even compete with ASA. In the years of "pinch and scrape", HIPS is a proper potential stock!

Let’s talk with data and application cases today, and see which more expensive plastics can be defeated by the upgraded HIPS?

1. ABS Alternatives

ABS is comparable to the king of home appliance applications, and almost every appliance has ABS applications from the outer shell to the inner parts. HIPS and ABS have the same shrinkage rate, so HIPS parts can be produced directly with the previous mold of ABS parts without modifying the injection mold.



Therefore, under the trend of rising prices of ABS raw materials, the price advantage of HIPS is obviously greater, but the strength and toughness of ordinary HIPS are lower than ABS. Thus, ordinary HIPS cannot completely replace ABS. So, HIPS can also achieve the same application effect as ABS only by strengthening the toughness and physical properties of HIPS. At present, there are relatively mature common ABS replacement cost reduction programs on the market. For example, Kumho-sunny Super-HIPS® HIPS N501; its notched impact strength is greater than 20KJ/m2, which is significantly higher than that of HIPS (10-14), and is on the same level as ordinary ABS, while the impact cracking ability is more than ABS.

It's not over yet, if you think it's not uncommon for HIPS to replace ordinary ABS. Let's take a look at the following applications, use HIPS instead of high-impact ABS, yes, when the largest weakness of HIPS is made up, there is nothing to do with ABS!

(Ultra) High toughness HIPS typical applications:

Common washing machine shell.

Air conditioning socket tongue, pressure plate, and exhaust port.

Refrigerator liner, door end cover, door shelf, etc.

2. ASA Alternatives

In some outdoor and semi-outdoor use occasions, the use of ABS or conventional HIPS will cause discoloration and brittleness in long-term use, affecting the appearance, while the cost of using ASA with good weather resistance will increase significantly.

At this time, the use of "weather-enhanced HIPS" is a cost-effective choice. I remember that when ABS went up wildly last year, the Super-HIPS® ultra-weather-resistant HIPS N505 on hand helped customers to complete the COSTDOWN index without any risk. The customer's product is a new energy charging pile, which has severe yellowing after long-term use. Let's take a look at the experimental comparison after 1008h of UV accelerated aging: the long-term anti-yellowing ability of N505 is much better than that of ABS, which is close to ASA. Combined with the cost advantage of HIPS itself, it is undoubtedly the best choice.

Typical applications of weather-resistant HIPS:

Air conditioners, charging piles, outdoor camera housings;

Electric motorcycle trunk parts, front guard.

3. As a special material for preventing abnormal noise

Home appliances, especially air conditioners, expand and contract during work, and plastic parts rub, which will produce abnormal noises. It has always been the hardest hit area for customer complaints, the old fans must know that Kumho-sunny has a set of popular "anti-abnormal noise materials" in the industry, which have been widely used by mainstream manufacturers. The solution is to reduce friction noise by increasing the damping of the material so that the energy of the friction-generated vibration is absorbed by the material itself. That is, the production labor cost of the plastering cloth is reduced, and the after-sales door-to-door service cost is also reduced.

However, the sharp rise in raw materials last year forced customers to force our engineers to find a more cost-effective solution. What's the reason? We searched for the options thousands of times in the crowd, and it didn't take much effort to get it: compared with other substrates, the anti-abnormal noise HIPS has lower human ear loudness! Come, look at the experimental data:

Typical applications of anti-abnormal noise HIPS:

It has been applied in many domestic head air conditioner manufacturers, and the inner frame of the on-hook air conditioner. In addition, high-end computer keyboards and vehicle interiors are all mass-produced and applied.

4. As chemical resistant material

In recent years, with the recurrence of the epidemic, the number of disinfecting scenes has increased.

This puts forward higher demands on the "chemical resistance" of many conventional materials. During the use of many products, the plastic casing may come into contact with various disinfectants, sunscreens, etc., which may damage the material, and chemical resistance also needs to be improved.

Editor has a Super-HIPS® ultra-chemical-resistant HIPS N521, which was originally used for medical product casings, and later also cross-border in the field of electric vehicles and new energy batteries. For spraying chemical reagents, it is as easy as taking a bath.

Typical applications of chemical resistant HIPS:

Medical device casings, and electric vehicle casings.
